CVE-2026-111958 · Royal MCP < 1.5.7 - Authentication Bypass via Preview Link Token
This page contains facts from public vulnerability sources. Check the original advisory before updating.
The Royal MCP WordPress plugin before 1.5.7 does not limit a preview-link token to the single preview it was issued for, so any party that obtains a valid token is authenticated as the token's owning user, an administrator in the default configuration, across the entire REST API with no nonce, leading to full site takeover.
