{"id":"GHSA-77qv-gh6f-pgh4","summary":"Command Injection in Limdu","details":"### Impact\nThe `trainBatch` function has a command injection vulnerability. Clients of the Limdu library are unlikely to be aware of this, so they might unwittingly write code that contains a vulnerability.\n\n### Patches\nPatched in version 0.9.5.\n\n### Workarounds\nDo not use trainBatch with classifiers that rely on shell execution, such as SVM Perf, SVM Linear or Adaboost\n\n### References\nNo","aliases":["CVE-2020-4066"],"modified":"2026-05-04T08:45:57.335613990Z","published":"2020-06-22T15:24:06Z","database_specific":{"cwe_ids":["CWE-78"],"severity":"LOW","github_reviewed":true,"github_reviewed_at":"2020-06-17T20:12:44Z","nvd_published_at":null},"references":[{"type":"WEB","url":"https://github.com/erelsgl/limdu/security/advisories/GHSA-77qv-gh6f-pgh4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-4066"},{"type":"WEB","url":"https://github.com/erelsgl/limdu/commit/03475a6a6bb253de6fad8f7f39cfb3504f11438d"},{"type":"PACKAGE","url":"https://github.com/erelsgl/limdu"}],"affected":[{"package":{"name":"limdu","ecosystem":"npm","purl":"pkg:npm/limdu"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.9.5"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 0.9.4","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2020/06/GHSA-77qv-gh6f-pgh4/GHSA-77qv-gh6f-pgh4.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:N"}]}
