GHSA-j8cv-x86q-rj85: Pipecat: Telephony WebSocket `/ws` Unauthenticated Call-Control Abuse via Attacker-Supplied Call SID

Summary

The pipecat development runner exposes a `/ws` WebSocket endpoint for telephony testing that accepts connections without authentication. An unauthenticated attacker can send a crafted Twilio stream-start message with an attacker-supplied `callSid`, causing the server to send a hang-up request to Twilio's REST API using the operator's own account credentials. The source says this may let an attacker terminate an active call on a victim's Twilio account if they know or obtain a valid call SID, and that equivalent sinks exist for Telnyx and Plivo.

Mitigation

The source does not state a fix yet. Check the original advisory for updates.
