CVE-2026-109382
El plugin WSP MCP AI Agents Connector para WordPress es vulnerable a la divulgación de información sensible en las versiones hasta la 2.9.5 inclusive. Esto se debe a que la herramienta MCP wsp_get_posts se registra sin ningún requisito de capacidad, mientras que el método authenticate() del endpoint MCP acepta a cualquier usuario que haya iniciado sesión, y a que la función de retrollamada wsp_execute_get_posts() respeta un argumento status=all proporcionado por el llamante, que se expande en un WP_Query sobre las entradas 'publish', 'draft', 'pending' y 'future' sin ningún filtro por autor o propiedad. Esto permite que atacantes autenticados, con acceso de nivel Subscriber o superior, lean los títulos, URL, autores, categorías, etiquetas y extractos de 40 palabras de todas las entradas no publicadas (borradores, pendientes o programadas) del sitio.

"value": "The WSP MCP AI Agents Connector plugin for WordPress is vulnerable to Sensitive Information Disclosure in versions up to, and including, 2.9.5. This is due to the wsp_get_posts MCP tool being registered with an empty capability requirement while the MCP endpoint's authenticate() method accepts any logged-in user, and the wsp_execute_get_posts() callback honouring a caller-supplied status=all argument that expands into a WP_Query over 'publish', 'draft', 'pending' and 'future' posts with no author or ownership filter. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read the titles, URLs, authors, categories, tags and 40-word excerpts of every unpublished (draft/pending/scheduled) post on the site."
