What is CVE-2026-22692?

October CMS versions before 3.7.13 and between 4.0.0 to 4.1.4 exhibit a sandbox bypass vulnerability linked to the optional Twig safe mode feature (CMS_SAFE_MODE). This flaw allows authenticated users with template editing permissions to manipulate certain methods on the collect() helper, thus circumventing intended sandbox protections. This vulnerability only impacts installations with CMS_SAFE_MODE enabled, which is disabled by default. To mitigate this risk, it is advised to either disable CMS_SAFE_MODE if untrusted template editing is unnecessary or to limit template editing permissions to trusted administrators. The issue has been resolved in subsequent releases, 3.7.13 and 4.1.5.

Affected Version(s)

october < 3.7.13 < 3.7.13

october >= 4.0.0, < 4.1.5 < 4.0.0, 4.1.5
