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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"cthackers","product":"adm-zip","versions":[{"version":"< 0.6.1","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","baseScore":7.1,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":1.8,"impactScore":5.2}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-07T20:53:29.301313Z","id":"CVE-2026-102282","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-732"}]}],"references":[{"url":"https://github.com/cthackers/adm-zip/commit/6a63c339b83c52915483efacda517660a7a7bf87","source":"security-advisories@github.com"},{"url":"https://github.com/cthackers/adm-zip/releases/tag/v0.6.1","source":"security-advisories@github.com"},{"url":"https://github.com/cthackers/adm-zip/security/advisories/GHSA-j5f4-cc29-5x44","source":"security-advisories@github.com"},{"url":"https://github.com/cthackers/adm-zip/security/advisories/GHSA-j5f4-cc29-5x44","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}
