CVE-2026-124969

Optimole <= 4.2.19 - Unauthenticated PHP Object Injection to Arbitrary File Deletion via 'comment_content'/'comment_agent' Parameter during Attachment Rename

The Optimole – Optimize Images | Convert WebP & AVIF | CDN & Lazy Load | Image Optimization plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the replace_urls_in_value function in all versions up to, and including, 4.2.19. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). Successful exploitation requires PEAR's Archive_Tar library to be present and loadable on the host (common in official WordPress Docker images and many PHP distributions), and an administrator must subsequently use the plugin's Rename control on any attachment after the attacker has staged a malicious payload in a comment. Successful exploitation additionally requires an action by an administrator — the attacker cannot trigger the vulnerability on their own.
