Assigner: WPScan
Reserved: 23.08.2026 Published: 02.09.2026 Updated: 02.09.2026

The Restrict User Access WordPress plugin before 2.8.1 does not normalise the REST API route before checking it against the routes its content protection covers, allowing unauthenticated users to bypass that protection and read restricted content and enumerate users.
