WordPress Plugin Vulnerabilities

King Addons for Elementor 51.1.56 - 51.1.80 - Author+ Missing Authorization via Image Optimizer

Description

The plugin does not perform per-object authorization checks on a group of image-optimization actions, gating them only on a coarse capability that lower-privileged users also hold and never confirming ownership of the targeted object, allowing authenticated users with author-level access and above to disclose absolute file paths for, overwrite the bytes of, and site-wide re-reference media belonging to other users, including administrators.
