## Affected

- wolfcms: through 0.8.3.1

## Description

Wolf CMS through 0.8.3.1 contains a remote code execution vulnerability in FileManagerController that allows authenticated attackers to create arbitrary PHP files by exploiting missing file extension validation in the create_file() and save() functions. Attackers with the file_manager_mkfile capability can write malicious PHP content into the web-accessible FILES_DIR directory and trigger execution by requesting the file over HTTP.
