SCA: security update for activestorage (GHSA-p9fm-f462-ggrg)

medium Tenable Self-Hosted Container Security Plugin ID 439227

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 proxy controller does not limit the number of byte ranges
 in an HTTP Range header. A request with thousands of small ranges causes disproportionate CPU usage
 compared to a normal request for the same file, possibly resulting in a DoS vulnerability. Versions
 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch. (CVE-2026-33658)

Solution

Update the activestorage library and its related packages to version 7.2.3.1 or later.
