SCA: security update for activestorage (GHSA-qcfx-2mfw-w4cg)
medium Tenable Cloud Security Plugin ID 439112
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, `DirectUploadsController` accepts arbitrary metadata from the client and
persists it on the blob. Because internal flags like `identified` and `analyzed` are stored in the same
metadata hash, a direct-upload client can set these flags to skip MIME detection and analysis. This allows
an attacker to upload arbitrary content while claiming a safe `content_type`, bypassing any validations
that rely on Active Storage's automatic content type identification. Versions 8.1.2.1, 8.0.4.1, and
7.2.3.1 contain a patch. (CVE-2026-33173)
Solution
Update the activestorage library and its related packages to version 7.2.3.1 or later.See Also
