CVE-2026-41470Public exploitNetwork attack vector

Service disruption via unauthenticated session-token replay

Published May 19, 2026 · Updated May 19, 2026

Authorization bypass in LIVE555 Streaming Media before 2026.04.22 allows remote attackers to disrupt RTSP service by replaying a valid Session token. The session dispatcher accepts PLAY, TEARDOWN, and PAUSE after token lookup without reauthenticating the current TCP connection, while PLAY binds callback state to that connection. Exploitation requires knowledge of a live token; replay from a second connection can terminate a victim stream or leave a stale callback pointer that crashes the server.
