Monthly
A Stored Cross-Site Scripting (XSS) vulnerability exists in the Sherk Custom Post Type Displays WordPress plugin (versions up to 1.2.1) where the 'title' shortcode attribute is insufficiently sanitized and directly concatenated into HTML output without escaping. Authenticated attackers with Contributor-level access or higher can inject arbitrary JavaScript that executes for all users viewing affected pages. The vulnerability has a CVSS score of 6.4 (Medium) with a local privilege requirement, making it exploitable by lower-privileged authenticated users rather than unauthenticated remote attackers.
