GHSA-ff5q-cc22-fgp4: WWBN AVideo has a CORS Origin Reflection Bypass via plugin/API/router.php and allowOrigin(true) Exposes Authenticated API Responses

The CORS origin validation fix in commit 986e64aad is incomplete. Two separate code paths still reflect arbitrary Origin headers with credentials allowed for all /api/* endpoints: (1) plugin/API/router.php lines 4-8 unconditionally reflect any origin before application code runs, and (2) allowOrigin(true) called by get.json.php and set.json.php reflects any origin with Access-Control-Allow-Credentials: true. An attacker can make cross-origin credentialed requests to any API endpoint and read authenticated responses containing user PII, email, admin status, and session-sensitive data.
