CVE-2026-100296
In Anjvision YSSD-RTMP-H5 firmware version 3.3.2.4, an empty-body POST to /setUserConfig, dispatched through the web server's SOAP-RPC handler, silently downgrades the administrator password to the default value and corrupts the in-memory authentication state until the device reloads. The handler does not verify the session's privilege level, so any authenticated user can trigger it.
