There is a possible sensitive session information leak in Active Storage. By
default, Active Storage sends a Set-Cookie
header along with the user’s
session cookie when serving blobs. It also sets Cache-Control
to public.
Certain proxies may cache the Set-Cookie, leading to an information leak.
This vulnerability has been assigned the CVE identifier CVE-2024-26144.
Versions Affected: >= 5.2.0, < 7.1.0
Not affected: < 5.2.0, > 7.1.0
Fixed Versions: 7.0.8.1, 6.1.7.7
A proxy which chooses to caches this request can cause users to share
sessions. This may include a user receiving an attacker’s session or vice
versa.
This was patched in 7.1.0 but not previously identified as a security
vulnerability.
All users running an affected release should either upgrade or use one of the
workarounds immediately.
The fixed releases are available at the normal locations.
Upgrade to Rails 7.1.X, or configure caching proxies not to cache the
Set-Cookie headers.
Thanks to tyage for reporting this!
