{"cve":"CVE-2026-102282","nvd":{"published":"2026-10-05T17:17:08.110","modified":"2026-10-07T21:17:07.297","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-732"],"references":["https://github.com/cthackers/adm-zip/commit/6a63c339b83c52915483efacda517660a7a7bf87","https://github.com/cthackers/adm-zip/releases/tag/v0.6.1","https://github.com/cthackers/adm-zip/security/advisories/GHSA-j5f4-cc29-5x44","https://github.com/cthackers/adm-zip/security/advisories/GHSA-j5f4-cc29-5x44"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-102282","score":0.00199,"percentile":0.09671,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-j5f4-cc29-5x44","url":"https://osv.dev/vulnerability/GHSA-j5f4-cc29-5x44","summary":"adm-zip extraction preserves SUID/SGID bits from untrusted ZIPs -> local privilege escalation","modified":"2026-10-08T10:56:40.691028011Z","packages":[{"ecosystem":"npm","name":"adm-zip","purl":"pkg:npm/adm-zip","ranges":["<0.6.1"],"fixed":["0.6.1"]}]}],"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).
