CVE-2026-33499Public exploitNetwork attack vector

Reflected XSS via unencoded unlockPassword attribute

Published Mar 23, 2026 · Updated Mar 23, 2026

Reflected XSS in WWBN AVideo 26.0 and earlier allows remote attackers to execute JavaScript via a crafted unlockPassword value. The forbiddenPage.php and warningPage.php templates concatenate the raw request value into an input element's value attribute without HTML encoding. Exploitation requires a victim to open a crafted link to a password-protected channel, after which script runs in the target origin and can read accessible session data or issue authenticated requests.
