SCA: security update for @apostrophecms/seo (GHSA-wf43-fpp3-cf65)

high Tenable Self-Hosted Container Security Plugin ID 445522

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. Versions up to and including 1.4.2 of
 the `@apostrophecms/seo` package injects the Google Analytics Tracking ID (`seoGoogleTrackingId`) and
 Google Tag Manager ID (`seoGoogleTagManager`) directly into `<script>` tag bodies using JavaScript
 template literals without any sanitization or validation. Any user with editor-level access (the default
 role for content managers) can set these fields to a malicious value, resulting in stored XSS that
 executes on every page for every visitor of the site. As of time of publication, no known patched versions
 are available. (CVE-2026-53608)

Solution

Update the @apostrophecms/seo library and its related packages to version 1.5.0 or later.
