{"id":"CVE-2026-102282","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-102282","generatedAt":"2026-10-28T00:59:28.210Z","title":"A zip crafted by an attacker can therefore produce an extracted binary with mode `04755`.","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.","published":"2026-10-05T17:17:08.000Z","lastModified":"2026-10-07T21:17:07.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},"cwe":["CWE-732"],"affected":[],"epss":{"score":0.00199,"percentile":0.09669,"date":"2026-10-26","history":[{"date":"2026-10-06","score":0.00149,"percentile":0.03558}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.20%).
