CVE-2026-54695Public exploitNetwork attack vector

Unauthenticated call termination via attacker-supplied identifiers

Published Jul 9, 2026 · Updated Jul 9, 2026

Missing authorization in Pipecat before 1.4.0 allows remote attackers to terminate active telephony calls through an exposed runner. The unauthenticated /ws handler copies a caller-controlled callSid into TwilioFrameSerializer, which uses the operator's credentials to send a hang-up request; Telnyx and Plivo follow the same pattern. Exploitation requires provider credentials, a reachable runner, and a valid call-control identifier, and the bounded consequence is interruption of the identified call.
