In Anjvision YSSD‑RTMP‑H5 firmware version 3.3.2.4, a hidden debug interface can be enabled through an authenticated request, allowing additional commands to be sent to a backend service. Once active, this pathway can unintentionally expose system‑level functionality that could be misused if crafted inputs reach the underlying command handler.
