## Description
Storage migration functionality, which allows the transfer of images
from one on-premises provider to another (e.g. AWS, Google, etc.) using
Active Storage.
I ran the unit and integration tests and they all passed correctly.
**The command to execute the migration is `FROM=from_service
TO=to_service rake storage:migrate`**
Fixes#7907
## Type of change
Please delete options that are not relevant.
- [x] New feature (non-breaking change which adds functionality)
## How Has This Been Tested?
I have tested the storage migration functionality by running the
provided unit and integration tests. Additionally, I manually tested the
migration process in a local development environment by following these
steps:
Set up two storage services (e.g., AWS S3 and Google Cloud Storage) with
valid configurations.
Execute the `FROM=local TO=amazon rake storage:migrate` task with
appropriate FROM and TO arguments to migrate blobs between the services.
Verified that the blobs were successfully transferred to the target
storage service.
Checked for any error messages or unexpected behavior during the
migration process.

## Description
This PR adds support for inline image uploads in the reply editor for
Email and Website (chat widget) channels.
Agents can now insert images inline between text and resize them
directly in the editor by dragging the bottom corner, similar to the
help center editor experience.
Image sizes are preserved through markdown using the `cw_image_width`
URL param and render correctly in both outgoing emails and chat widget
messages.
Agents can also paste copied images directly into Email or Website
replies using **Shift+Cmd+V** (Shift+Ctrl+V on Windows/Linux). The image
gets inserted inline at the cursor position and supports resizing just
like uploaded images. Regular **Cmd+V / Ctrl+V** behavior remains
unchanged and continues to add images as attachments, so both inline and
attachment flows are supported.

Self-hosted installations can now opt SafeFetch into private-network
access after SSRF hardening. The default remains unchanged: private IP
destinations are blocked unless the instance owner explicitly enables
private-network requests with `SAFE_FETCH_ALLOW_PRIVATE_NETWORK=true`.
Fixes https://linear.app/chatwoot/issue/CW-7131
Fixes https://github.com/chatwoot/chatwoot/issues/14489
Fixes https://github.com/chatwoot/chatwoot/issues/14494
## How to use
For self-hosted installations that need API inbox webhooks, or other
SafeFetch-backed requests, to call trusted private services, enable
private-network access with a single environment variable:
```bash
SAFE_FETCH_ALLOW_PRIVATE_NETWORK=true
```
This is disabled by default. Enable it only when the instance owner
controls the deployment network and trusts the configured URLs.

`spec/lib/safe_fetch_spec.rb` has been flaking intermittently under
full-suite runs with errors like:
```
expected SafeFetch::FileTooLargeError, got #<SafeFetch::FileTooLargeError: exceeded 1048576 bytes>
```
The class name on both sides is identical — yet RSpec reports a
mismatch. This PR replaces the constant-identity assertions in this spec
with a name-based matcher so the comparison stops depending on the live
Class object's identity. We have made a similar fix earlier, but that
wasn't addressing the core of the issue in #14139.
**How to reproduce:** The flake only surfaces under load. Running the
spec in isolation almost always passes, here's a [run failing in
CI](https://github.com/chatwoot/chatwoot/actions/runs/25852294516/job/75961520248?pr=14370)
## What's actually going on
Three facts combine:
1. **Test env reloads classes.** `config/environments/test.rb` sets
`cache_classes = false` so Zeitwerk reloads autoloadable code on demand.
2. **`lib/` is on the reloadable autoload tree.**
`config/application.rb` adds `lib` to `eager_load_paths`, which (with
`eager_load = false` in test) makes it lazily loaded by Zeitwerk's
*main* (reloading) autoloader. `lib/safe_fetch/` lives under that
umbrella.
3. **RSpec's `raise_error(Klass)` snapshots the Class object.**
`raise_error` matcher captures `Klass` (a specific `Class` instance)
when the matcher is built. At raise time it compares with `Module#===`,
which is identity-based.
When the executor between examples triggers
`Rails.application.reloader.reload!`, Zeitwerk does
`remove_const(:SafeFetch)` and re-installs an autoload trigger. The next
access produces a **fresh** `Class` object for
`SafeFetch::FileTooLargeError` — same name, different identity. The
matcher's snapshot now points at the dead Class, and the live raise
produces the new one. Identity fails, even though the error is
semantically correct.
This bites SafeFetch specifically because:
- SafeFetch is a *namespace* with 7 nested error classes — one reload
invalidates all of them.
- The spec contains 14+ `raise_error(SafeFetch::Foo)` assertions — many
chances to land in a reload window.
- SafeFetch is exercised by request-driven code (webhook delivery,
avatar fetch). Earlier specs in the suite warm up the reloader
machinery, which then fires during this spec.
Other custom-error specs don't visibly flake because their consumers
`rescue ConstName => e` (dynamic class lookup at raise time, walks the
ancestor chain via `Module#===` *at the moment of raise*, with no
captured snapshot), rather than RSpec's snapshot-then-compare pattern.
## What this PR does
Adds a small local helper to the spec that matches by class name string,
not by Class identity:
```ruby
def safe_fetch_error(name, message_pattern = nil)
satisfy("raise SafeFetch::#{name}#{" matching #{message_pattern.inspect}" if message_pattern}") do |error|
error.class.name == "SafeFetch::#{name}" &&
(message_pattern.nil? || message_pattern.match?(error.message))
end
end
```
Every `raise_error(described_class::FooError)` becomes
`raise_error(safe_fetch_error('FooError'))`. Class names are strings;
string equality survives any number of reloads. The semantic assertion
("this raised the right kind of error") is preserved.
This is the pattern CLAUDE.md already endorses for this codebase:
> Specs in parallel/reloading environments: prefer comparing
`error.class.name` over constant class equality when asserting raised
errors.
## Why this approach (even though it's suboptimal)
To be honest with reviewers: **this is a workaround, not a root-cause
fix.** Future spec authors who use `raise_error(SafeFetch::Foo)` in
other files will hit the same flake. The "real" fix removes the failure
mode at the source rather than dodging it per-spec.
Here's the menu of options we considered and the tradeoffs:
### Option A — Spec-side name matcher (this PR)
- **What:** the helper above.
- **Pro:** one-file change, zero blast radius beyond the spec.
- **Pro:** matches CLAUDE.md's documented stance.
- **Con:** every new spec touching reloadable error classes needs to
remember this pattern. It's a discipline tax, not a structural fix.
- **Verdict:** chosen for this PR.
### Option B — Pin SafeFetch outside Zeitwerk
```ruby
# config/application.rb
Rails.autoloaders.main.ignore(
Rails.root.join('lib/safe_fetch.rb'),
Rails.root.join('lib/safe_fetch'),
)
require Rails.root.join('lib/safe_fetch')
```
- **Pro:** real root-cause fix. `SafeFetch::*` constants become
process-lifetime stable. The spec helper becomes unnecessary, every
assertion in any spec works correctly.
- **Pro:** preserves the public API exactly.
- **Con:** loses hot-reload for SafeFetch in dev (need server restart to
see edits).
- **Con:** modifies `application.rb`, which has cross-team review
weight.
- **Verdict:** rejected for scope reasons in this PR; a sensible
follow-up.
### Option C — Move error classes to a non-reloadable location
Define top-level error classes in
`config/initializers/safe_fetch_errors.rb`. Initializers run once at
boot, constants are never reloaded.
- **Pro:** identity-stable errors, no spec helper needed.
- **Con:** API change — `SafeFetch::FileTooLargeError` becomes
`SafeFetchFileTooLargeError` (or similar). Every consumer's `rescue`
clause has to update.
- **Con:** namespace pollution at top-level.
- **Verdict:** rejected. The constraint of touching initializers is what
motivated the simpler PR.
### Option D — Vendor SafeFetch as a path gem
Move `lib/safe_fetch/` → `vendor/gems/safe_fetch/` with a gemspec.
Bundler `require`s gems once; Zeitwerk has zero involvement.
- **Pro:** structurally the most correct fix. Same identity stability as
Option B, no Zeitwerk plumbing required.
- **Pro:** zero API change for consumers.
- **Con:** larger refactor (6+ files moved, gemspec authored,
Gemfile/Gemfile.lock updated).
- **Con:** SafeFetch becomes harder to iterate on in dev (gem-style
edit-then-restart loop).
- **Verdict:** rejected for scope in this PR; the cleanest long-term
home for a security primitive.
### Option E — Drop custom errors, return a `Result`
Refactor SafeFetch to yield a result hash (`{ ok: true, ... }` / `{ ok:
false, kind: :unsafe_url, ... }`) instead of raising for anticipated
outcomes. Failure kinds become symbols, which are interned for the
process lifetime.
- **Pro:** eliminates the failure mode at its true root — there are no
custom exception classes to reload, anywhere.
- **Pro:** forces explicit, exhaustive handling at every call site — a
feature for a security primitive.
- **Pro:** spec assertions become data assertions (`expect(result).to
match(ok: false, kind: :too_large)`), which are robust against any
reload, any reordering.
- **Con:** paradigm shift away from the exception-driven style used
everywhere else in the codebase.
- **Con:** every consumer rewrites their `rescue` block into
pattern-matched handling.
- **Verdict:** rejected for scope in this PR; the architecturally
cleanest answer if we ever revisit SafeFetch's API.
## Why we're shipping A despite knowing B–E are better
This flake has been chewing CI time intermittently and previously took a
partial fix (#14139). We need it stable *now*. Options B–E are real
refactors with broader review surface (`application.rb`, consumer code,
or the lib's public contract). Option A:
- Costs nothing — one helper, mechanical replacements.
- Doesn't preclude any of B/C/D/E later. The helper goes away cleanly
once a root-cause fix lands.
- Aligns with the project's documented guidance for this scenario.
When SafeFetch next gets a substantive change, that's the right moment
to fold in B or D. Until then, the spec is stable and CI gets its time
back.
## What changed
- `spec/lib/safe_fetch_spec.rb`: added `safe_fetch_error(name,
message_pattern = nil)` helper; converted all 14
`raise_error(described_class::FooError[, /regex/])` assertions to
`raise_error(safe_fetch_error('FooError'[, /regex/]))`.
Embed templates interpolate regex captures from user-authored article
URLs into HTML attribute values. CommonMark's angle-bracket link
destination syntax allows characters that the capture regexes don't
filter, so the unescaped substitution could produce malformed attribute
output. Escaping at substitution time keeps the render deterministic
regardless of the URL.
### How was this tested?
Added specs.

When a customer responds to a bot's interactive prompt (input_select,
input_csat, form, input_email) from the widget, the response shows up in
the Chatwoot agent UI but is not reflected in the linked Slack channel —
Slack only ever shows the original question. This happens because the
widget submits the answer as an UPDATE to the original message (writing
`content_attributes.submitted_values` or `submitted_email`), but the
Slack hook only listened to `message.created`, so updates were ignored.

## Description
This PR fixes an issue where signature images (with
`?cw_image_height=...`) render at their original large size in the email
bubble.
### Cause
Renderer output:
```html
<img src="..." height="24px" width="auto" />
```
Email UI and clients (Gmail, Outlook) apply CSS like:
`img { max-width: 100%; height: auto; }`
This overrides `height="24px"`.
Other channels work because they use inline styles (`style="height:
24px;"`).
### Solution
Use inline style instead:
```html
<img src="..." style="height: 24px;" />
```
### Why backend fix
* Fixes root cause and aligns Ruby + JS renderers
* Works in both Chatwoot UI and recipient inboxes
* Covers all email-rendered content
* Minimal change

This fixes the agent-bot webhook delivery path so transient upstream
failures follow the expected delivery lifecycle. Existing fallback
behavior is preserved, and fallback actions are applied only after
delivery attempts are exhausted.
To reproduce, configure an agent-bot webhook endpoint to return 429/500
for message events. Before this fix, failure handling could be applied
too early; after this fix, delivery attempts complete first and then
existing fallback handling runs.
Tested with:
- bundle exec rspec spec/jobs/agent_bots/webhook_job_spec.rb
spec/lib/webhooks/trigger_spec.rb
- bundle exec rubocop spec/jobs/agent_bots/webhook_job_spec.rb
spec/lib/webhooks/trigger_spec.rb

CSAT templates for WhatsApp are submitted as Utility, but Meta may
reclassify them as Marketing based on content, which can significantly
increase messaging costs.
This PR introduces a Captain-powered CSAT template analyzer for
WhatsApp/Twilio WhatsApp that predicts utility fit, explains likely
risks, and suggests safer rewrites before submission. The flow is manual
(button-triggered), Captain-gated, and applies rewrites only on explicit
user action. It also updates UX copy to clearly set expectations: the
system submits as Utility, Meta makes the final categorization decision.
Fixes
https://linear.app/chatwoot/issue/CW-6424/ai-powered-whatsapp-template-classifier-for-csat-submissionshttps://github.com/user-attachments/assets/8fd1d6db-2f91-447c-9771-3de271b16fd9
Adds an account-level setting `keep_pending_on_bot_failure` to control
whether conversations should move from pending to open when agent bot
webhooks fail.
Some users experience occasional message drops and don't want
conversations to automatically reopen due to transient bot failures.
This setting gives accounts control over that behavior. This is a
temporary setting which will be removed in future once a proper fix for
it is done, so it is not added in the UI.
Creating a Linear issue from Chatwoot fails with a GraphQL parse error
when the title, description, or search term contains double quotes. For
example, a description like `the sender is "Bot"` produces this broken
query:
```graphql
issueCreate(input: { description: "the sender is "Bot"" })
```
Linear's API rejects this with `Syntax Error: Expected ":", found
String`. This affects issue creation, issue linking, and issue search —
any flow where user-provided text is interpolated into a GraphQL query.
The `graphql_value` helper was only escaping newlines (`\n`) but not
quotes, backslashes, or other characters that are meaningful inside a
GraphQL string literal. On top of that, `issue_link` and `search_issue`
bypassed `graphql_value` entirely, using raw string interpolation
instead.
The fix replaces the manual `gsub` escaping with Ruby's `to_json`, which
produces a properly escaped, double-quoted string that handles all
special characters. This is a minimal, well-understood substitution —
`to_json` on a Ruby string returns a valid JSON string literal, which is
also a valid GraphQL string literal since GraphQL uses the same escaping
rules. The `issue_link` mutation and `search_issue` query are updated to
route their parameters through `graphql_value` instead of raw
interpolation.
The `team_entities_query` and `linked_issues` methods in `queries.rb`
also use raw interpolation, but their inputs are system-generated IDs
and URLs rather than user-provided text, so they're left as-is to keep
this change focused.
## Description
Implements comprehensive search functionality with advanced filtering
capabilities for Chatwoot (Linear: CW-5956).
This PR adds:
1. **Time-based filtering** for contacts and conversations (SQL-based
search)
2. **Advanced message search** with multiple filters
(OpenSearch/Elasticsearch-based)
- **`from` filter**: Filter messages by sender (format: `contact:42` or
`agent:5`)
- **`inbox_id` filter**: Filter messages by specific inbox
- **Time range filters**: Filter messages using `since` and `until`
parameters (Unix timestamps in seconds)
- **90-day limit enforcement**: Automatically limits searches to the
last 90 days to prevent performance issues
The implementation extends the existing `Enterprise::SearchService`
module for advanced features and adds time filtering to the base
`SearchService` for SQL-based searches.

## Technical Implementation
### SQL-Based Search (Contacts, Conversations, Articles)
- Uses PostgreSQL `ILIKE` queries by default
- Optional GIN index support via `search_with_gin` feature flag for
better performance
- Time filtering uses `last_activity_at` for contacts/conversations
- Returns paginated results (15 per page)
### Advanced Search (Messages)
- Powered by OpenSearch/Elasticsearch via Searchkick gem
- Requires `OPENSEARCH_URL` environment variable
- Requires `advanced_search` account feature flag
- Enforces 90-day lookback limit via
`Limits::MESSAGE_SEARCH_TIME_RANGE_LIMIT_DAYS`
- Validates inbox access permissions before filtering
- Returns paginated results (15 per page)
---
## Type of change
- [x] New feature (non-breaking change which adds functionality)
- [x] Enhancement (improves existing functionality)
---
## How Has This Been Tested?
### Unit Tests
- **Contact Search Tests**: 3 new test cases for time filtering
(`since`, `until`, combined)
- **Conversation Search Tests**: 3 new test cases for time filtering
- **Message Search Tests**: 10+ test cases covering:
- Individual filters (`from`, `inbox_id`, time range)
- Combined filters
- Permission validation for inbox access
- Feature flag checks
- 90-day limit enforcement
- Error handling for exceeded time limits
### Test Commands
```bash
# Run all search controller tests
bundle exec rspec spec/controllers/api/v1/accounts/search_controller_spec.rb
# Run search service tests (includes enterprise specs)
bundle exec rspec spec/services/search_service_spec.rb
```
### Manual Testing Setup
A rake task is provided to create 50,000 test messages across multiple
inboxes:
```bash
# 1. Create test data
bundle exec rake search:setup_test_data
# 2. Start OpenSearch
mise elasticsearch-start
# 3. Reindex messages
rails runner "Message.search_index.import Message.all"
# 4. Enable feature flag
rails runner "Account.first.enable_features('advanced_search')"
# 5. Test via API or Rails console
```

## Additional Notes
### Requirements
- **OpenSearch/Elasticsearch**: Required for advanced message search
- Set `OPENSEARCH_URL` environment variable
- Example: `export OPENSEARCH_URL=http://localhost:9200`
- **Feature Flags**:
- `advanced_search`: Account-level flag for message advanced search
- `search_with_gin` (optional): Account-level flag for GIN-based SQL
search
### Performance Considerations
- 90-day limit prevents expensive long-range queries on large datasets
- GIN indexes recommended for high-volume search on SQL-based resources
- OpenSearch/Elasticsearch provides faster full-text search for messages
### Breaking Changes
- None. All new parameters are optional and backward compatible.
### Frontend Integration
- Frontend PR tracking advanced search UI will consume these endpoints
- Time range pickers should convert JavaScript `Date` to Unix timestamps
(seconds)
- Date conversion: `Math.floor(date.getTime() / 1000)`
### Error Handling
- Invalid `from` parameter format is silently ignored (filter not
applied)
- Time range exceeding 90 days returns `422` with error message
- Missing `q` parameter returns `422` (existing behavior)
- Unauthorized inbox access is filtered out (no error, just excluded
from results)

# Pull Request Template
## Description
This PR includes,
1. **Channel-specific formatting and menu options** for the rich reply
editor.
2. **Removal of the plain reply editor** and full **standardization** on
the rich reply editor across all channels.
3. **Fix for multiple canned responses insertion:**
* **Before:** The plain editor only allowed inserting canned responses
at the beginning of a message, making it impossible to combine multiple
canned responses in a single reply. This caused inconsistent behavior
across the app.
* **Solution:** Replaced the plain reply editor with the rich
(ProseMirror) editor to ensure a unified experience. Agents can now
insert multiple canned responses at any cursor position.
4. **Floating editor menu** for the reply box to improve accessibility
and overall user experience.
5. **New Strikethrough formatting option** added to the editor menu.

We’ve been watching Sidekiq workers climb from ~600 MB at boot to
1.4–1.5 GB after an hour whenever attachment-heavy jobs run. This PR is
an experiment to curb that growth by streaming attachments instead of
loading the whole blob into Ruby: reply-mailer inline attachments,
Telegram uploads, and audio transcriptions now read/write in chunks. If
this keeps RSS stable in production we’ll keep it; otherwise we’ll roll
it back and keep digging

# Changelog
When an agent bot webhook fails, we now flip any pending conversation
back to an open state so a human agent can pick
it up immediately. There will be an clear activity message giving the
team clear visibility into what went
wrong. This keeps customers from getting stuck in limbo when their
connected bot goes offline.
# Testing instructions
1. Initial setup: Create an agent bot with a working webhook URL and
connect it to a test inbox. Send a message from a
contact (e.g., via the widget) so a conversation is created; it should
enter the Pending state while the bot handles
the reply.
2. Introduce failure: Edit that agent bot and swap the webhook URL for a
dummy endpoint that will fail. Have the same
contact send another message in the existing conversation. Because the
webhook call now fails, the conversation should flip from Pending back
to Open, making it visible to agents. Also verify the activity message
3. New conversation check: With the dummy URL still in place, start a
brand-new conversation from a contact. When the
bot tries (and fails) to respond, confirm that the conversation appears
immediately as Open rather than remaining Pending. Also the activity
message is visible
4. Subsequent messages in open conversations will show no change

Fixes https://linear.app/chatwoot/issue/CW-5752/fix-nomethoderror-when-processing-video-files-in-slack-integration
#### Problem
When users shared video files (like MP4) through Slack, the `file_type`
method in `SlackMessageHelper` would return `nil` for unsupported file
types. This caused a `NoMethodError (undefined method 'to_sym' for nil)`
when the attachment was being processed, as the system expected a symbol
value for the `file_type` attribute.
#### Solution
- Added video file type support in the `file_type` method case statement
- Added `else` clause to default unknown file types to `:file` instead
of returning `nil`
- This ensures `file_type` always returns a symbol, preventing the
`to_sym` error
Fixes
https://linear.app/chatwoot/issue/CW-5646/add-support-for-grouped-file-uploads-in-slack
Previously, when sending multiple attachments to Slack, we uploaded them
one by one. For example, sending 5 images would result in 5 separate
Slack messages. This created clutter and a poor user experience, since
Slack displayed each file as an individual message.
This PR updates the implementation to group all attachments from a
message and send them as a single Slack message. As a result,
attachments now appear together in one grouped block, providing a much
cleaner and more intuitive experience for users.
**Before:**
Each file uploaded as a separate Slack message.
<img width="400" height="800" alt="before"
src="https://github.com/user-attachments/assets/c8c7f666-549b-428f-bd19-c94e39ed2513"
/>
**After:**
All files from a single message grouped and displayed together in one
Slack message (similar to how Slack natively handles grouped uploads).
