CVE-2024-0687Network attack vector

Unauthenticated content disclosure via unprotected REST API

Published Mar 13, 2024 · Updated Apr 8, 2026

Improper access control in Restrict User Access 2.5 and earlier allows remote attackers to read restricted posts and pages via the REST API. The plugin enforces Access Conditions on front-end requests but omits equivalent checks when WordPress returns post and page content through REST API responses. The flaw is reachable without authentication when protected content exists and the REST API is accessible, exposing content without permitting modification.
