October Rain has a Twig Sandbox Bypass via Collection Methods
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 ### References - Reported by Łukasz Rybak
