Summary
October Rain has a Twig Sandbox Bypass via Collection Methods
Details

A sandbox bypass vulnerability was identified 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.

Impact

  • Bypass of Twig sandbox restrictions
  • Only affects installations with CMS_SAFE_MODE enabled (disabled by default)
  • Requires authenticated backend access with CMS template editing permissions

Patches

The vulnerability has been patched in v4.1.5 and v3.7.13. All users who have enabled safe mode are encouraged to upgrade to the latest patched version.

Workarounds

If upgrading immediately is not possible: - Disable CMS_SAFE_MODE if untrusted template editing is not required - Restrict CMS template editing permissions to fully trusted administrators only
