Vulnerability from cvelistv5 – Published: 2026-04-14 16:48 – Updated: 2026-04-14 19:42

Title

October CMS: Twig Sandbox Bypass via Collection Methods

Summary

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.

Severity ?

GHSA-M5QG-JC75-4JP6

Vulnerability from github – Published: 2026-04-14 20:02 – Updated: 2026-04-14 20:02

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
