CVE-2026-126076actionpack10. Nov 2026
### Impact `ActionDispatch::Session::CacheStore` writes a session back to the cache at the end of each request that loaded it, without checking that the session's cache entry still exists. When a concurrent request destroys the session, through `reset_session` on logout or by deleting its cache entry on the server, a request that loaded the session earlier and finishes later restores it under its original session ID. Logout and server-side revocation could therefore fail to…
CVE-2026-126075activesupport10. Nov 2026
### Impact `ActiveSupport::MessagePack` serializes an `ActiveSupport::SafeBuffer` as its bytes alone and deserializes it as a new `SafeBuffer`, so a buffer that is no longer `html_safe?` (for example, one mutated in place with `gsub!`) is restored as `html_safe`. If such a buffer holds untrusted input and is stored through a MessagePack serializer, rendering it after it is loaded bypasses ERB auto-escaping, possibly leading to XSS. Applications on Rails 8.1 are affected if…
CVE-2026-126074activestorage10. Nov 2026
Active Storage makes it simple to upload and reference files in cloud services and attach those files to Active Record objects. Prior to 8.1.4.1 and 8.0.5.2, ActiveStorage::Filename#base and #extension_with_delimiter, and therefore #extension, pass the stored filename unmodified to File.basename and File.extname, which raise ArgumentError when the name contains a NUL byte. Active Storage stores the client-supplied filename verbatim, so a user who is permitted to upload an…
CVE-2026-126073actionpack10. Nov 2026
### Impact Action Pack negotiates the format of a rendered response from the `Accept`, `X-Requested-With` and, for XHR requests without `Accept`, `Content-Type` request headers, but `ActionController::Rendering#_set_vary_header` adds `Vary: Accept` only when the request carries a usable `Accept` header and the response has no `Vary` header yet. A response to a request without `Accept`, or to an XHR request, therefore omits the headers that selected its representation, and a…
CVE-2026-126071activestorage10. Nov 2026
Active Storage makes it simple to upload and reference files in cloud services and attach those files to Active Record objects. From 8.0 until 8.0.5.2 and 8.1.4.1, when Active Storage serves a file through its proxy controllers, ActiveStorage::Streaming#send_blob_stream handles an error from the storage service by calling head to send a 404 or 500 response. If the error occurs after the first chunk has been written, the response is already committed, and head replaces the…
CVE-2026-126068actionmailbox10. Nov 2026
### Impact The Action Mailbox Mailgun ingress authenticates a request with an HMAC of the `timestamp` and `token` parameters concatenated without a separator, and `ActionMailbox::Ingresses::Mailgun::InboundEmailsController::Authenticator#recent?` rejects only timestamps more than 2 minutes in the past. Because the signature does not fix the boundary between the two values, a captured signed request can be presented with a timestamp far in the future, which the ingress then…
CVE-2026-126067actionpack10. Nov 2026
### Impact Action Pack session stores other than `ActionDispatch::Session::CookieStore` (`CacheStore`, `MemCacheStore`, and third-party stores built on `AbstractStore`, `AbstractSecureStore` or the session mixins) write the session cookie without a `SameSite` attribute, regardless of `config.action_dispatch.cookies_same_site_protection`, which defaults to `:lax`. Only `CookieStore` applies the configured policy. In browsers that do not treat a cookie without the attribute as…
CVE-2026-126066fast-xml-parser10. Nov 2026
### Summary With the non-default stopNodes option, a stop node's body with many " " anywhere after makes readStopNodeData() rescan the entire remaining input from every " ` exists - `OrderedObjParser.js:812-818` — on failure, `i` isn't advanced, so the next ` ` lookahead is neither cached nor bounded — `n` copies of ` ` means `n` scans over the remaining input, O(n²) work, before it finally throws. **Fix** 1. Throw immediately in `readStopNodeData()` when `readTagExp()`…
