Executive Summary

The vulnerability in the Meta-box GalleryMeta WordPress plugin is due to a missing capability check on the 'mb_gallery' custom post type. This allows authenticated users with Author-level access or higher to create and publish galleries without proper authorization, leading to unauthorized modification of data.

Impact Analysis

This vulnerability can impact you by allowing users with Author-level access or above to create and publish galleries without proper permission checks. This unauthorized modification could lead to unwanted or malicious content being published on your WordPress site, potentially affecting site integrity and user trust.

Mitigation Strategies

To mitigate this vulnerability, immediately update the Meta-box GalleryMeta plugin to a version later than 3.0.1 once available, as versions up to and including 3.0.1 are vulnerable. Additionally, restrict Author-level and above user permissions carefully, since authenticated users with Author-level access can exploit this vulnerability to create and publish galleries. Monitoring and limiting user capabilities related to the 'mb_gallery' custom post type can help reduce risk until a patch is applied. [2, 3]
