{"cve":"CVE-2026-44716","nvd":{"published":"2026-06-10T00:16:53.110","modified":"2026-10-06T21:10:00.173","status":"Analyzed","description":"Pipecat is an open-source Python framework for building real-time voice and multimodal conversational agents. From version 0.0.90 to before version 1.2.0, a path traversal vulnerability exists in Pipecat's development runner (src/pipecat/runner/run.py). When the runner is started with the --folder flag, it exposes a GET /files/{filename:path} download endpoint. The filename path parameter is concatenated directly onto args.folder with no containment check. Starlette normalises literal ../ sequences in URLs, but %2F-encoded slashes bypass this normalisation: the path parameter is URL-decoded after routing, so ..%2F..%2Fetc%2Fpasswd resolves to a path two levels above args.folder. An attacker with network access to the runner can read any file the pipecat process has permission to access — including SSH private keys, credentials, and system files — with a single unauthenticated HTTP request. This issue has been patched in version 1.2.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-22"],"references":["https://github.com/pipecat-ai/pipecat/commit/7519c26ac5508573c35fa3a9c4717b013993d129","https://github.com/pipecat-ai/pipecat/pull/4417","https://github.com/pipecat-ai/pipecat/releases/tag/v1.2.0","https://github.com/pipecat-ai/pipecat/security/advisories/GHSA-3363-2ph6-35wh"],"products":["pipecat:pipecat"],"source":"nvd","synced_at":"2026-10-19T22:38:48.522727527+00:00"},"epss":{"cve":"CVE-2026-44716","score":0.00423,"percentile":0.36287,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-3363-2ph6-35wh","url":"https://osv.dev/vulnerability/GHSA-3363-2ph6-35wh","summary":"Pipecat: Path Traversal in Pipecat Runner `/files` Endpoint — Arbitrary File Read via `%2F`-Encoded Separator","modified":"2026-07-13T16:42:50.468184485Z","packages":[{"ecosystem":"PyPI","name":"pipecat-ai","purl":"pkg:pypi/pipecat-ai","ranges":[">=0.0.90 <1.2.0"],"fixed":["1.2.0"]}]},{"id":"PYSEC-2026-2877","url":"https://osv.dev/vulnerability/PYSEC-2026-2877","summary":"Pipecat: Path Traversal in Pipecat Runner `/files` Endpoint — Arbitrary File Read via `%2F`-Encoded Separator","modified":"2026-07-13T16:32:57.455550871Z","packages":[{"ecosystem":"PyPI","name":"pipecat-ai","purl":"pkg:pypi/pipecat-ai","ranges":[">=0.0.90 <1.2.0"],"fixed":["1.2.0"]}]}],"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).
