SCA: security update for activestorage (GHSA-9xrj-h377-fr87)
critical Tenable Cloud Security Plugin ID 439111
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions
8.1.2.1, 8.0.4.1, and 7.2.3.1, Active Storage's `DiskService#path_for` does not validate that the resolved
filesystem path remains within the storage root directory. If a blob key containing path traversal
sequences (e.g. `../`) is used, it could allow reading, writing, or deleting arbitrary files on the
server. Blob keys are expected to be trusted strings, but some applications could be passing user input as
keys and would be affected. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch. (CVE-2026-33195)
Solution
Update the activestorage library and its related packages to version 7.2.3.1 or later.See Also
