Recommendation: Plan a near-term fix — a public PoC already exists.
The Royal MCP WordPress plugin before 1.4.26 does not perform capability checks on the majority of its MCP tools after token authentication, allowing authenticated users with a low-privileged role such as Subscriber to read private content, enumerate all users and their roles, and create, modify, or delete content owned by other users.
