CVE-2026-88793: YouTube Embed lets unauthenticated callers store scripts through a public AJAX nonce

YouTube Embed 10.0 through 10.3 exposes an AJAX action without an authorization check and prints its nonce on every front-end page. An unauthenticated attacker can obtain that nonce, submit attacker-controlled data for storage, and have the unescaped value execute as a web script when affected content is viewed, including in an administrator's session. The authoritative export does not identify the AJAX action, storage field, rendered context, or parameter names.
