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.","state":0,"publishedAt":"2026-06-26T16:44:29.768+00:00","modifiedAt":"2026-06-30T19:59:09.065+00:00","affected":[{"ecosystem":"Vendor product","name":"extract-zip","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"max-mapper\",\n                    \"product\": \"extract-zip\",\n                    \"defaultStatus\": \"affected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThan\": \"*\",\n                            \"versionType\": \"custom\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"HIGH"},{"system":"CVSS 4.0","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,"severity":"HIGH"}],"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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-56876","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-56876","identifiers":["CVE-2026-56876"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
