Versions prior to 3.1.1, 2.1.3, and 1.16.5 are vulnerable to symlink validation bypass if the destination directory is predictable with a specific tarball. This issue has been patched in version 3.1.1, 2.1.4, and 1.16.6. A workaround involves using the ignore option on non files/directories.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":null,"cwes":["CWE-22","CWE-61"],"references":["https://github.com/mafintosh/tar-fs/commit/0bd54cdf06da2b7b5b95cd4b062c9f4e0a8c4e09","https://github.com/mafintosh/tar-fs/security/advisories/GHSA-vj76-c3g6-qr5v","https://lists.debian.org/debian-lts-announce/2025/09/msg00028.html"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:10:08.713834912+00:00"},"epss":{"cve":"CVE-2025-59343","score":0.00553,"percentile":0.46196,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-vj76-c3g6-qr5v","url":"https://osv.dev/vulnerability/GHSA-vj76-c3g6-qr5v","summary":"tar-fs has a symlink validation bypass if destination directory is predictable with a specific tarball","modified":"2026-09-10T03:50:28.767326235Z","packages":[{"ecosystem":"npm","name":"tar-fs","purl":"pkg:npm/tar-fs","ranges":[">=3.0.0 <3.1.1"],"fixed":["3.1.1"]},{"ecosystem":"npm","name":"tar-fs","purl":"pkg:npm/tar-fs","ranges":[">=2.0.0 <2.1.4"],"fixed":["2.1.4"]},{"ecosystem":"npm","name":"tar-fs","purl":"pkg:npm/tar-fs","ranges":["<1.16.6"],"fixed":["1.16.6"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
