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.","published":"2026-06-09T23:07:25.868Z","modified":"2026-08-12T03:51:20.539491400Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":{"score":0.00423,"percentile":0.35055,"asOf":"2026-08-12"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"pipecat-ai","fixedVersion":"1.2.0"}],"fix":{"url":"https://github.com/pipecat-ai/pipecat/commit/7519c26ac5508573c35fa3a9c4717b013993d129","label":"pipecat-ai/pipecat@7519c26"},"references":[{"type":"WEB","url":"https://github.com/pipecat-ai/pipecat/releases/tag/v1.2.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44716.json"},{"type":"ADVISORY","url":"https://github.com/pipecat-ai/pipecat/security/advisories/GHSA-3363-2ph6-35wh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44716"},{"type":"FIX","url":"https://github.com/pipecat-ai/pipecat/commit/7519c26ac5508573c35fa3a9c4717b013993d129"},{"type":"FIX","url":"https://github.com/pipecat-ai/pipecat/pull/4417"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:20.539491400Z"}}
