CVE-2026-78153 Details
Description
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.
A vulnerability exists in the Restrict User Access WordPress plugin in versions prior to 2.8.1.
