Details
As written in the advisory (Markdown source, shown as plain text).
### 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
