CVE-2026-40925 · WWBN AVideo has CSRF in configurationUpdate.json.php Enables Full Site Configuration Takeover Including Encoder URL and SMTP Credentials

Diese Seite enthält Fakten aus öffentlichen Sicherheitsquellen. Lesen Sie vor dem Aktualisieren die Originalmeldung.

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.
