Summary
WWBN AVideo has CSRF in configurationUpdate.json.php Enables Full Site Configuration Takeover Including Encoder URL and SMTP Credentials
Details

WWBN AVideo is an open source video platform. In versions 29.0 and prior, objects/configurationUpdate.json.php (also routed via /updateConfig) persists dozens of global site settings from $_POST but protects the endpoint only with User::isAdmin(). It does not call forbidIfIsUntrustedRequest(), does not verify a globalToken, and does not validate the Origin/Referer header. Because AVideo intentionally sets session.cookie_samesite=None to support cross-origin iframe embedding, a logged-in administrator who visits an attacker-controlled page will have the browser auto-submit a cross-origin POST that rewrites the site's encoder URL, SMTP credentials, site <head> HTML, logo, favicon, contact email, and more in a single request. Commit f9492f5e6123dff0292d5bb3164fde7665dc36b4 contains a fix.
