CVE-2026-40775

The Royal MCP Secure AI Connector plugin for WordPress has a security flaw that allows unverified individuals to bypass standard access controls because a crucial capability check is absent from a specific function in versions prior to and including 1.4.2, enabling them to execute an illicit operation without proper authorization. This oversight creates a vulnerability through which unauthorized actions can be carried out by attackers who are not authenticated.
