AI-suggested

A fix is available in October CMS versions 3.7.13 and 4.1.5. Users should upgrade to these or later versions to remediate the vulnerability. If upgrading immediately is not possible, users can mitigate risk by disabling the CMS_SAFE_MODE feature if untrusted template editing is not required and by restricting CMS template editing permissions strictly to fully trusted administrators. Since CMS_SAFE_MODE is disabled by default, ensuring it remains disabled unless necessary reduces exposure.

Description

October is a Content Management System (CMS) and web platform. Versions prior to 3.7.13 and versions 4.0.0 through 4.1.4 contain a sandbox bypass vulnerability in the optional Twig safe mode feature (CMS_SAFE_MODE). Certain methods on the collect() helper were not properly restricted, allowing authenticated users with template editing permissions to bypass sandbox protections. Exploitation requires authenticated backend access with CMS template editing permissions and only affects installations with CMS_SAFE_MODE enabled (disabled by default). This issue has been fixed in versions 3.7.13 and 4.1.5. To workaround this issue, users can disable CMS_SAFE_MODE if untrusted template editing is not required, and restrict CMS template editing permissions to fully trusted administrators only.
