SCA: security update for activestorage (GHSA-r46p-8f7g-vvvg)

high Tenable Self-Hosted Container Security Plugin ID 439114

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, when serving files through Active Storage's proxy delivery mode, the proxy
 controller loads the entire requested byte range into memory before sending it. A request with a large or
 unbounded Range header (e.g. `bytes=0-`) could cause the server to allocate memory proportional to the
 file size, possibly resulting in a DoS vulnerability through memory exhaustion. Versions 8.1.2.1, 8.0.4.1,
 and 7.2.3.1 contain a patch. (CVE-2026-33174)

Solution

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