Description

The Optimole – Optimize Images | Convert WebP & AVIF | CDN & Lazy Load | Image Optimization plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.1.0 via the /wp-json/optml/v1/move_image REST API endpoint due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Author-level access and above, to offload media that doesn't belong to them.
