The Image Resizer On The Fly WordPress plugin (versions ≤1.1) contains a critical arbitrary file deletion vulnerability in its 'delete' task that allows unauthenticated attackers to remove arbitrary files from the server without authentication. This vulnerability can facilitate remote code execution by deleting critical files such as wp-config.php, leading to complete WordPress installation compromise. With a CVSS score of 9.1 and network-accessible attack vector requiring no user interaction or privileges, this represents a critical risk to all unpatched installations.
