          "value": "WWBN AVideo is an open source video platform. In versions up to and including 29.0, objects/sendEmail.json.php exposes two branches depending on whether contactForm=1 is submitted. When the parameter is omitted, the endpoint sets $sendTo to an attacker-supplied email and, for unauthenticated callers, uses the site\u0027s own contact email as the message From:/Reply-To:. The endpoint is explicitly allow-listed as a \"public write action\" in objects/functionsSecurity.php (line 885), so it requires no authentication or CSRF token. An unauthenticated attacker (solving a captcha) can force the site\u0027s own SMTP infrastructure to send attacker-composed emails to arbitrary recipients with the site\u0027s legitimate sender address, passing SPF/DKIM/DMARC for the site\u0027s domain \u2014 ideal for targeted phishing and brand impersonation. Commit 4e3709895857a5857f0edb46b0ee984de0d9e1a2 contains an updated fix."
