0 CVE-2026-33500 is a stored cross-site scripting (XSS) vulnerability in WWBN AVideo versions up to 26.0. The issue arises from improper sanitization of markdown links in user comments, allowing attackers to inject malicious JavaScript via markdown link syntax. This bypasses the custom sanitization implemented for raw HTML tags because the markdown parser disables safeMode, which normally filters unsafe URLs. Exploitation requires low privileges and user interaction but can lead to confidentiality and integrity impacts by executing arbitrary scripts in other users' browsers. A patch addressing this vulnerability has been committed but not yet widely deployed. Organizations using affected versions should apply the patch promptly and review comment sanitization controls. The CVSS score is 5.4 (medium severity). Join the discussion | CVE Database V5 | 03/23/2026, 16:24:52 UTC Added: 03/23/2026, 16:30:54 UTC |
