{"id":"CVE-2026-102282","published":"2026-10-05T17:17:08.110","lastModified":"2026-10-07T21:17:07.297","description":"adm-zip is a JavaScript library for creating and extracting ZIP archives in Node.js. 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.","cvssScore":7.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","cwes":["CWE-732"],"vendors":[],"products":[],"references":[{"url":"https://github.com/cthackers/adm-zip/commit/6a63c339b83c52915483efacda517660a7a7bf87","tags":[]},{"url":"https://github.com/cthackers/adm-zip/releases/tag/v0.6.1","tags":[]},{"url":"https://github.com/cthackers/adm-zip/security/advisories/GHSA-j5f4-cc29-5x44","tags":[]},{"url":"https://github.com/cthackers/adm-zip/security/advisories/GHSA-j5f4-cc29-5x44","tags":[]}],"exploitRefs":[{"url":"https://github.com/cthackers/adm-zip/commit/6a63c339b83c52915483efacda517660a7a7bf87","tags":[]},{"url":"https://github.com/cthackers/adm-zip/releases/tag/v0.6.1","tags":[]},{"url":"https://github.com/cthackers/adm-zip/security/advisories/GHSA-j5f4-cc29-5x44","tags":[]},{"url":"https://github.com/cthackers/adm-zip/security/advisories/GHSA-j5f4-cc29-5x44","tags":[]}],"hasPoc":true,"ai":null}
