SCA: security update for october/system (GHSA-6qmh-j78v-ffp7)

medium Tenable Cloud Security Plugin ID 440384

Description

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

- October is a Content Management System (CMS) and web platform. Versions prior to 3.7.14 and 4.1.10 contain
a Stored Cross-Site Scripting (XSS) vulnerability in the Backend Editor Settings. The Markup Classes
fields (used for paragraph styles, inline styles, table styles, etc.) did not sanitize input to valid CSS
class name characters. Malicious values were rendered unsanitized in Froala editor dropdown menus,
allowing JavaScript execution when any user opened a RichEditor. Exploitation could lead to privilege
escalation if a superuser opens any RichEditor during routine content editing (e.g., editing a blog post),
and requires authenticated backend access with editor settings permissions. This issue has been fixed in
versions 3.7.14 and 4.1.10. To workaround this issue, restrict editor settings permissions to fully
trusted administrators only (CVE-2026-24906)

Solution

Update the october/system library and its related packages to version 3.7.14 or later.
