Prior to 0.6.1, adm-zip applies the Unix permission bits stored in a zip entry directly to the extracted file via `fs.chmodSync()` when `keepOriginalPermission=true` is passed to `extractAllTo()`/`extractEntryTo()` — and it never filters the setuid/setgid/sticky bits out of those bits. A zip crafted by an attacker can therefore produce an extracted binary with mode `04755`. When extraction runs as root (the default posture in Docker builds, CI runners, and privileged install steps — the exact environments where this flag is used), the resulting root-owned setuid file is executed later by a lesser-privileged user, turning the attacker's code into a root execution. Version 0.6.1 fixes the issue.","state":0,"publishedAt":"2026-10-05T17:00:00.25+00:00","modifiedAt":"2026-10-07T20:53:52.156+00:00","affected":[{"ecosystem":"Vendor product","name":"adm-zip","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"cthackers\",\n                    \"product\": \"adm-zip\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.6.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","score":7.1,"severity":"HIGH"}],"references":["https://github.com/cthackers/adm-zip/security/advisories/GHSA-j5f4-cc29-5x44","https://github.com/cthackers/adm-zip/commit/6a63c339b83c52915483efacda517660a7a7bf87","https://github.com/cthackers/adm-zip/releases/tag/v0.6.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-102282","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-102282","identifiers":["CVE-2026-102282"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
