Package
  october/system (Composer)

Affected versions
2.2.33, 3.0.65

Patched versions
2.2.34, 3.0.66


Description

Impact
This vulnerability only affects installations that rely on the safe
mode restriction, commonly used when providing public access to the
admin panel. Assuming an attacker has access to the admin panel and
permission to open the "Editor" section, they can bypass the Safe
Mode (cms.safe_mode) restriction to introduce new PHP code in a CMS
template using a specially crafted request.


Patches
The issue has been patched in v2.2.34 and v3.0.66
