SCA: security update for @apostrophecms/ai-helper (GHSA-527g-ff96-x6wj)

medium Tenable Cloud Security Plugin ID 476362

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. From 1.0.0-beta.10 until 1.0.0-beta.13
 of the AI helper, an editor with image-generation capability can create a base64-generated image record
 without a stored provider URL and invoke image acceptance on a deployment using local relative storage
 with no trusted global base URL. The server resolves the fixed uploads path against a request-controlled
 Host-derived origin, enabling bounded server-side requests to an attacker-selected host, port, and HTTP
 origin, but not arbitrary-path retrieval or the stored-provider and absolute-storage configurations. This
 issue is fixed in AI helper 1.0.0-beta.13. (CVE-2026-113671)

Solution

Update the @apostrophecms/ai-helper library and its related packages to version 1.0.0-beta.13 or later.
