Technical details
The vulnerability is a missing per-object authorization (broken access control, CWE-862) in the image optimizer functionality. The plugin gates image-optimization actions only on a coarse capability check that lower-privileged users also possess, and fails to verify ownership of the targeted media object. An authenticated user with author-level access or above can exploit this to disclose absolute file paths, overwrite file contents, and re-reference media across the entire site without ownership validation. The vulnerability affects versions before 51.1.81, and is patched in 51.1.81.
