Hardens Active Storage handling on Rails 7.1 by filtering internal direct-upload metadata keys and limiting proxy range requests, while keeping audio playback on redirect URLs so large recordings are not routed through the proxy limiter. Closes - CVE-2026-33173 - CVE-2026-33174 - CVE-2026-33658 Why Rails 7.1 does not currently have patched releases for these Active Storage advisories, and Chatwoot exposes Active Storage direct-upload endpoints and media URLs. This keeps the Rails dependency unchanged while adding small local mitigations until Rails can be upgraded to 7.2.3.1+. What changed - Filters `identified`, `analyzed`, and `composed` from direct-upload blob metadata. - Limits Active Storage proxy range requests to one range under 100 MB. - Uses redirect URLs for inline audio attachments so normal playback of large recordings avoids the proxy streaming path. - Adds scoped bundle-audit ignores for the locally mitigated Active Storage advisories and the remaining Rails advisories that are not reachable through current Chatwoot usage. How to test - Upload an attachment from the dashboard reply composer and confirm it sends successfully. - Upload an attachment from the website widget and confirm it appears in the conversation. - POST a direct-upload request with `blob.metadata.identified`, `blob.metadata.analyzed`, and `blob.metadata.composed`; confirm those keys are not persisted while custom metadata remains. - Play an audio/call-recording attachment and confirm the audio URL loads through Active Storage redirect rather than proxy. - Run `bundle exec bundle audit check -v`. --------- Co-authored-by: Muhsin Keloth <muhsinkeramam@gmail.com>
