Description

LIVE555 before 2026.04.22 contains an authorization bypass vulnerability in RTSP session command handling that allows attackers to replay valid Session tokens from unauthenticated connections. Attackers who obtain a valid Session token can issue PLAY and TEARDOWN commands from a second TCP connection without authentication, causing server crashes through virtual function call errors or disrupting active streams by terminating victim sessions.
