What is CVE-2026-119059?

The Content Egg plugin for WordPress is exposed to unauthorized data modification due to a flawed capability check in the ajaxUpdateProducts() function. This vulnerability arises from the use of an unvalidated user-supplied post ID, which permits authenticated users with contributor-level access or higher to alter product data for posts, including those owned by administrators. Failure to properly check permissions allows for potential manipulation of the site's content, compromising data integrity and overall security.

Affected Version(s)
