{"cve":"CVE-2026-54695","nvd":{"published":"2026-07-09T19:17:06.540","modified":"2026-10-25T17:10:00.197","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H","score":6.5},"cwes":["CWE-862"],"references":["https://github.com/pipecat-ai/pipecat/commit/3032da53434c5ef01d368654b3551cf21c50dec9","https://github.com/pipecat-ai/pipecat/commit/88440676996e5e548e1aecea5d565e1c48ccf6fa","https://github.com/pipecat-ai/pipecat/pull/4660","https://github.com/pipecat-ai/pipecat/releases/tag/v1.4.0","https://github.com/pipecat-ai/pipecat/security/advisories/GHSA-j8cv-x86q-rj85"],"products":["pipecat:pipecat"],"source":"nvd","synced_at":"2026-10-25T17:50:06.907763985+00:00"},"epss":{"cve":"CVE-2026-54695","score":0.00564,"percentile":0.46588,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-j8cv-x86q-rj85","url":"https://osv.dev/vulnerability/GHSA-j8cv-x86q-rj85","summary":"Pipecat: Telephony WebSocket `/ws` Unauthenticated Call-Control Abuse via Attacker-Supplied Call SID","modified":"2026-07-13T16:42:49.142702823Z","packages":[{"ecosystem":"PyPI","name":"pipecat-ai","purl":"pkg:pypi/pipecat-ai","ranges":[">=0.0.77 <1.4.0"],"fixed":["1.4.0"]}]},{"id":"PYSEC-2026-2878","url":"https://osv.dev/vulnerability/PYSEC-2026-2878","summary":"Pipecat: Telephony WebSocket `/ws` Unauthenticated Call-Control Abuse via Attacker-Supplied Call SID","modified":"2026-07-13T16:32:57.452938993Z","packages":[{"ecosystem":"PyPI","name":"pipecat-ai","purl":"pkg:pypi/pipecat-ai","ranges":[">=0.0.77 <1.4.0"],"fixed":["1.4.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
