## Technical details

The request handler in Fanvil x7a firmware 2.6.0.1182 lacks CSRF protection on all state-changing endpoints, allowing cross-origin requests to be processed without validation. An attacker can craft a malicious webpage that, when visited by an authenticated user of the phone's web interface, submits forged requests to modify device settings or trigger actions. No authentication bypass is required; exploitation relies on an existing authenticated session.
