Vulnerability Title
WWBN AVideo has CSRF in configurationUpdate.json.php Enables Full Site Configuration Takeover Including Encoder URL and SMTP Credentials
Source: NVD (National Vulnerability Database)
Vulnerability Description
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.

Vulnerability Description
