SCA: security update for apostrophe (GHSA-m2m5-rw3w-cwmj)

medium Tenable Self-Hosted Container Security Plugin ID 476393

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - ApostropheCMS is an open-source Node.js content management system. Prior to 4.33.0, an unauthenticated
 attacker can send a crafted link whose query string is automatically parsed by apos.http.parseQuery when
 an authenticated victim loads a page with the admin bundle. The parser accepts the special __proto__,
 constructor, and prototype path keys, allowing browser prototype mutation that can reach an unsafe DOM
 sink and execute script in the victim's session; anonymous visitors do not load the affected admin
 context. This issue is fixed in version 4.33.0. (CVE-2026-113659)

Solution

Update the apostrophe library and its related packages to version 4.33.0 or later.
