WSP MCP <= 2.9.5 - Authenticated (Subscriber+) Sensitive Information Disclosure via Broken Access Control to 'wsp_get_posts' MCP Tool
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Subscriber-level access and above, to read the titles, URLs, authors, categories, tags and 40-word excerpts of every unpublished (draft/pending/scheduled) post on the site.
