CVE-2026-68554

Coturn (open-source TURN/STUN server) prior to 4.15.0 is vulnerable to an on-path STUN message truncation attack. The root cause is that the server-side parser in src/server/ns_turn_server.c continues processing attributes after the MESSAGE-INTEGRITY field. Since the HMAC covers only the message ...
