CVE-2026-88793NVD

Description

The YouTube Embed WordPress plugin from 10.0 to 10.3 does not perform any authorisation check on one of its AJAX actions, relying only on a nonce it prints on every front-end page, and does not escape the stored data before rendering it, allowing unauthenticated attackers to store arbitrary web scripts which will execute in the session of any user viewing the affected content, including an administrator.
