Name of the Vulnerable Software and Affected Versions Meow Gallery versions prior to 5.4.5

Description The Meow Gallery plugin for WordPress allows unauthorized modification of data because of a missing capability check on the REST API endpoint "/wp-json/meow-gallery/v1/save shortcode". Authenticated attackers with Author-level access or higher can arbitrarily create or overwrite gallery shortcode records by providing a user-controlled id value. The system performs database updates without verifying if the user is authorized to modify the specific gallery record or create a new one.

Recommendations Update the plugin to version 5.4.5 or later. As a temporary mitigation, restrict access to the "/wp-json/meow-gallery/v1/save shortcode" endpoint for users with Author-level permissions.
