CVE-2026-82647
WWBN AVideo Cross-Site Request Forgery via sendEmail.json.php
Description
WWBN AVideo contains a cross-site request forgery vulnerability in sendEmail.json.php that allows authenticated administrators to send mail from the site's contact address by bypassing origin checks and captcha validation. Attackers can craft a malicious web page that, when visited by an authenticated admin, sends emails with attacker-controlled subject and body to arbitrary recipients, passing SPF/DKIM/DMARC validation for phishing and brand impersonation attacks.
