## What is CVE-2026-100296?

CVE-2026-100296 is a high-severity missing authorization vulnerability in Anjvision YSSD-RTMP-H5, published on 29 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

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.

Weakness: CWE-754 (Improper Check for Unusual or Exceptional Conditions)
