When processing a malicious zip file containing a symlink with a relative path like '../../../../etc/passwd', extract-zip will extract the symlink without validation, allowing it to point outside the extraction directory. Depending on how extract-zip is used, an attacker could read or write to arbitrary files.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","score":8.6},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","score":8.1},"cwes":["CWE-22","CWE-61"],"references":["https://github.com/ziad626/extract-zip-security-research/security/advisories/GHSA-x7jf-2287-qcpf","https://raw.githubusercontent.com/cisagov/CSAF/develop/csaf_files/IT/white/2026/va-26-177-01.json","https://www.cve.org/CVERecord?id=CVE-2026-56876"],"products":["max-mapper:extract-zip"],"source":"nvd","synced_at":"2026-10-25T17:50:06.907763985+00:00"},"epss":{"cve":"CVE-2026-56876","score":0.00526,"percentile":0.44267,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-jmr9-qjv8-65gv","url":"https://osv.dev/vulnerability/GHSA-jmr9-qjv8-65gv","summary":"extract-zip unvalidated symlink path traversal","modified":"2026-09-10T03:51:08.769710691Z","packages":[{"ecosystem":"npm","name":"extract-zip","purl":"pkg:npm/extract-zip","ranges":["<=2.0.1"],"fixed":[]}]}],"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).
