A YAML parser can execute arbitrary Python commands resulting in command execution because load is used where safe_load should have been used. An attacker can insert Python into loaded YAML to trigger this vulnerability.","published":"2017-11-08T03:29:00.247Z","modified":"2026-07-08T15:10:50.185410Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"pyanyapi","fixedVersion":"0.6.1"}],"fix":{"url":"https://github.com/Stranger6667/pyanyapi/commit/810db626c18ebc261d5f4299d0f0eac38d5eb3cf","label":"Stranger6667/pyanyapi@810db62"},"references":[{"type":"WEB","url":"https://pypi.python.org/pypi/pyanyapi/0.6.1"},{"type":"ADVISORY","url":"https://github.com/Stranger6667/pyanyapi/releases/tag/0.6.1"},{"type":"ADVISORY","url":"https://joel-malwarebenchmark.github.io/blog/2017/11/08/cve-2017-16616-yamlparser-in-pyanyapi/"},{"type":"REPORT","url":"https://github.com/Stranger6667/pyanyapi/issues/41"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2017-16616"},{"type":"WEB","url":"https://github.com/Stranger6667/pyanyapi/commit/810db626c18ebc261d5f4299d0f0eac38d5eb3cf"},{"type":"PACKAGE","url":"https://github.com/Stranger6667/pyanyapi"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-vg8g-jpm9-jh8r"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/pyanyapi/PYSEC-2017-23.yaml"},{"type":"WEB","url":"https://joel-malwarebenchmark.github.io/blog/2017/11/08/cve-2017-16616-yamlparser-in-pyanyapi"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-08T15:10:50.185410Z"}}
