What is CVE-2026-7252?

The WP-Optimize plugin for WordPress has a vulnerability due to inadequate file path validation in its unscheduled_original_file_deletion function. This flaw affects all versions up to and including 4.5.2. Authenticated users with author-level permissions can exploit this vulnerability to delete arbitrary files on the server, potentially leading to remote code execution. The 'original-file' meta key, being publicly accessible, allows these users to manipulate it freely through the Edit Media interface or the REST API, raising significant security concerns.
