Summary

MyTube is a self-hosted downloader and player for several video websites. A vulnerability present in version 1.7.65 and poetntially earlier versions allows unauthenticated users to bypass the mandatory authentication check in the roleBasedAuthMiddleware. By simply not providing an authentication cookie (making req.user undefined), a request is incorrectly passed through to downstream handlers. All users running MyTube with loginEnabled: true are impacted. This flaw allows an attacker to access and modify application settings via /api/settings, change administrative and visitor passwords, and access other protected routes that rely on this specific middleware. The problem is patched in v1.7.66. MyTube maintainers recommend all users upgrade to at least version v1.7.64 immediately to secure
