{"id":"CVE-2020-15271","aliases":["GHSA-c84h-w6cr-5v8q","PYSEC-2020-61"],"url":"https://o3.security/vulnerability/CVE-2020-15271","summary":"Markdown-supplied Shell Command Execution","details":"In lookatme (python/pypi package) versions prior to 2.3.0, the package automatically loaded the built-in \"terminal\" and \"file_loader\" extensions. Users that use lookatme to render untrusted markdown may have malicious shell commands automatically run on their system. This is fixed in version 2.3.0. As a workaround, the `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.","published":"2020-10-26T18:15:14.480Z","modified":"2026-07-09T01:06:47.022523Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"PyPI","name":"lookatme","fixedVersion":"2.3.0"}],"fix":{"url":"https://github.com/d0c-s4vage/lookatme/commit/72fe36b784b234548d49dae60b840c37f0eb8d84","label":"d0c-s4vage/lookatme@72fe36b"},"references":[{"type":"ADVISORY","url":"https://github.com/d0c-s4vage/lookatme/releases/tag/v2.3.0"},{"type":"ADVISORY","url":"https://github.com/d0c-s4vage/lookatme/security/advisories/GHSA-c84h-w6cr-5v8q"},{"type":"ADVISORY","url":"https://pypi.org/project/lookatme/#history"},{"type":"FIX","url":"https://github.com/d0c-s4vage/lookatme/commit/72fe36b784b234548d49dae60b840c37f0eb8d84"},{"type":"EVIDENCE","url":"https://github.com/d0c-s4vage/lookatme/pull/110"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-09T01:06:47.022523Z"}}
