WP Headless CMS Framework <= 1.15 - Unauthenticated Protection Mechanism Bypass

CVE CVE-2025-11260

Researcher Jonas Benjamin Friedli
Description

The WP Headless CMS Framework plugin for WordPress is vulnerable to protection mechanism bypass in all versions up to, and including, 1.15. This is due to the plugin only checking for the existence of the Authorization header in a request when determining if the nonce protection should be bypassed. This makes it possible for unauthenticated attackers to access content they should not have access to.
