{"id":"CVE-2026-54695","summary":"Pipecat: Telephony WebSocket `/ws` Unauthenticated Call-Control Abuse via Attacker-Supplied Call SID","details":"Pipecat is an open-source Python framework for building real-time voice and multimodal conversational agents. Prior to 1.4.0, the pipecat development runner registers a /ws WebSocket endpoint for telephony testing that accepts connections without authentication, reads an attacker-supplied callSid from a Twilio stream-start handshake in src/pipecat/runner/utils.py, and passes it to TwilioFrameSerializer so the server can issue an authenticated Twilio REST API hang-up request with the server operator's credentials; equivalent unauthenticated call-control sinks exist for Telnyx and Plivo. This issue is fixed in version 1.4.0.","aliases":["GHSA-j8cv-x86q-rj85","PYSEC-2026-2878"],"modified":"2026-08-12T03:51:29.252769407Z","published":"2026-07-09T18:52:33.008Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54695.json"},"references":[{"type":"WEB","url":"https://github.com/pipecat-ai/pipecat/releases/tag/v1.4.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54695.json"},{"type":"ADVISORY","url":"https://github.com/pipecat-ai/pipecat/security/advisories/GHSA-j8cv-x86q-rj85"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54695"},{"type":"FIX","url":"https://github.com/pipecat-ai/pipecat/commit/3032da53434c5ef01d368654b3551cf21c50dec9"},{"type":"FIX","url":"https://github.com/pipecat-ai/pipecat/commit/88440676996e5e548e1aecea5d565e1c48ccf6fa"},{"type":"FIX","url":"https://github.com/pipecat-ai/pipecat/pull/4660"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pipecat-ai/pipecat","events":[{"introduced":"0"},{"fixed":"3a69d3f79cedc8daab2a57e44a17d34a18f1c096"},{"fixed":"3032da53434c5ef01d368654b3551cf21c50dec9"},{"fixed":"88440676996e5e548e1aecea5d565e1c48ccf6fa"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.4.0"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:pipecat:pipecat:*:*:*:*:*:python:*:*"}}],"versions":["v1.3.0","v1.2.1","v1.2.0","v1.1.0","v1.0.0","v0.0.108","v0.0.95","v0.0.107","v0.0.106","v0.0.105","v0.0.104","v0.0.103","v0.0.102","v0.0.101","v0.0.100","v0.0.99","v0.0.98","v0.0.97","v0.0.96","v0.0.94","v0.0.93","v0.0.92","v0.0.91","v0.0.90","v0.0.89","v0.0.88","v0.0.87","v0.0.86","v0.0.85","v0.0.84","v0.0.83","v0.0.82","v0.0.81","v0.0.80","v0.0.79","v0.0.78","v0.0.77","v0.0.76","v0.0.75","v0.0.74","v0.0.73","v0.0.72","v0.0.71","v0.0.70","v0.0.69","v0.0.68","v0.0.67","v0.0.66","v0.0.65","v0.0.64","v0.0.63","v0.0.62","v0.0.61","v0.0.60","v0.0.59","v0.0.58","v0.0.57","v0.0.56","v0.0.55","v0.0.54","v0.0.53","v0.0.52","v0.0.50","v0.0.49","v0.0.48","v0.0.47","v0.0.46","v0.0.45","v0.0.44","v0.0.43","v0.0.42","v0.0.41","v0.0.40","v0.0.39","v0.0.38","v0.0.37","v0.0.36","v0.0.35","v0.0.34","v0.0.33","v0.0.32","v0.0.31","v0.0.30","v0.0.29","v0.0.28","v0.0.27","v0.0.26","v0.0.25","v0.0.24","v0.0.23","v0.0.22","v0.0.21","v0.0.20","v0.0.19","v0.0.18","v0.0.17","v0.0.16","v0.0.15","v0.0.14","v0.0.13","v0.0.12","v0.0.11","v0.0.10","v0.0.9","v0.0.8","v0.0.7","v0.0.6","v0.0.5","v0.0.4","v0.0.3","v0.0.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-54695.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:L/A:H"}]}
