SCA: security update for apostrophe (GHSA-6h5j-32cf-4253)

critical Tenable Self-Hosted Container Security Plugin ID 445523

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. In versions up to and including 4.30.0,
 `apos.util.set()` traverses dot-notation paths without sanitizing `__proto__`, allowing an authenticated
 editor to write arbitrary values to `Object.prototype` via the `$pullAll` patch operator. A confirmed
 gadget in `publicApiCheck()` causes this to bypass authorization on all piece-type REST API endpoints for
 every subsequent unauthenticated request, for the lifetime of the Node.js process. As of time of
 publication, no known patched versions are available. (CVE-2026-53609)

Solution

Update the apostrophe library and its related packages to version 4.31.0 or later.
