Wolf CMS through 0.8.3.1 contains an authorization bypass vulnerability in BackupRestoreController that allows authenticated non-administrative users to access restricted backup functionality due to a PHP operator precedence flaw in the permission check expression. Attackers can exploit the incorrect evaluation of the access control expression to create, download, and restore backups without administrative privileges.

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 createfile() and save() functions. Attackers with the filemanagermkfile capability can write malicious PHP content into the web-accessible FILESDIR directory and trigger execution by requesting the file over HTTP.
