Title

LIVE555 < 2026.04.22 RTSP Server Authorization Bypass via Session Token

Summary

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.
