Users that use lookatme to render untrusted markdown may have malicious shell commands automatically run on their system.\n\n### Patches\n\nUsers should upgrade to lookatme versions 2.3.0 or above.\n\n### Workarounds\n\nThe `lookatme/contrib/terminal.py` and `lookatme/contrib/file_loader.py` files may be manually deleted. Additionally, it is always recommended to be aware of what is being rendered with lookatme.\n\n### References\n\n* https://github.com/d0c-s4vage/lookatme/pull/110\n* https://github.com/d0c-s4vage/lookatme/releases/tag/v2.3.0\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n\n* Open an issue in [d0c-s4vage/lookatme](https://github.com/d0c-s4vage/lookatme)","aliases":["CVE-2020-15271","PYSEC-2020-61"],"modified":"2026-03-13T22:15:44.506502Z","published":"2020-10-27T17:59:54Z","related":["CVE-2020-15271"],"database_specific":{"cwe_ids":["CWE-78"],"github_reviewed":true,"github_reviewed_at":"2020-10-26T18:07:46Z","severity":"CRITICAL","nvd_published_at":null},"references":[{"type":"WEB","url":"https://github.com/d0c-s4vage/lookatme/security/advisories/GHSA-c84h-w6cr-5v8q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-15271"},{"type":"WEB","url":"https://github.com/d0c-s4vage/lookatme/pull/110"},{"type":"WEB","url":"https://github.com/d0c-s4vage/lookatme/commit/72fe36b784b234548d49dae60b840c37f0eb8d84"},{"type":"PACKAGE","url":"https://github.com/d0c-s4vage/lookatme"},{"type":"WEB","url":"https://github.com/d0c-s4vage/lookatme/releases/tag/v2.3.0"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/lookatme/PYSEC-2020-61.yaml"},{"type":"WEB","url":"https://pypi.org/project/lookatme/#history"}],"affected":[{"package":{"name":"lookatme","ecosystem":"PyPI","purl":"pkg:pypi/lookatme"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.3.0"}]}],"versions":["0.0.2","0.1.0","0.1.1","0.2.0","0.3.0","0.4.0","0.5.0","1.0.0","1.0.1","1.1.0","1.1.1","1.2.0","1.2.1","1.3.0","2.0.0","2.1.0","2.2.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2020/10/GHSA-c84h-w6cr-5v8q/GHSA-c84h-w6cr-5v8q.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:N/SC:H/SI:H/SA:N"}]}
