What is CVE-2026-67206?

Wolf CMS versions up to 0.8.3.1 are susceptible to a remote code execution vulnerability due to inadequate file extension validation in the FileManagerController. This flaw enables authenticated attackers with the 'file_manager_mkfile' capability to craft arbitrary PHP files. By exploiting this vulnerability, an attacker can upload malicious PHP content to a publicly accessible directory (FILES_DIR). Triggering the execution of the uploaded files can lead to unauthorized actions within the web application. It is crucial for users of Wolf CMS to assess their installations and implement necessary security measures to mitigate this risk.

Affected Version(s)
