{"id":"GHSA-xpm8-98mx-h4c5","summary":"Unsafe deserialization in MLAlchemy","details":"An exploitable vulnerability exists in the YAML parsing functionality in the parse_yaml_query method in parser.py in MLAlchemy before 0.2.2. When processing YAML-Based queries for data, 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.","aliases":["CVE-2017-16615","PYSEC-2017-19"],"modified":"2025-02-14T05:43:13.434696Z","published":"2018-07-13T16:01:07Z","database_specific":{"cwe_ids":[],"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2020-06-16T22:03:55Z","nvd_published_at":null},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2017-16615"},{"type":"WEB","url":"https://github.com/thanethomson/MLAlchemy/issues/1"},{"type":"WEB","url":"https://github.com/thanethomson/MLAlchemy/commit/bc795757febdcce430d89f9d08f75c32d6989d3c"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/mlalchemy/PYSEC-2017-19.yaml"},{"type":"PACKAGE","url":"https://github.com/thanethomson/MLAlchemy"},{"type":"WEB","url":"https://joel-malwarebenchmark.github.io/blog/2017/11/08/cve-2017-16615-critical-restful-web-applications-vulnerability"}],"affected":[{"package":{"name":"mlalchemy","ecosystem":"PyPI","purl":"pkg:pypi/mlalchemy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.2.2"}]}],"versions":["0.1.0","0.1.1","0.1.2","0.1.3","0.2.0","0.2.1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2018/07/GHSA-xpm8-98mx-h4c5/GHSA-xpm8-98mx-h4c5.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
