CVE-2026-102282 · Severity: high · CVSS 7.1 · Published 2026-10-05

adm-zip, a Node.js library for reading and writing ZIP files, fails to filter special permission bits (setuid, setgid, sticky) when extracting archives with the keepOriginalPermission flag enabled. An attacker can craft a malicious ZIP file containing a binary with setuid bits set; when extracted by root (common in Docker builds and CI pipelines), this produces a root-owned executable that executes with elevated privileges when run by an unprivileged user later, enabling arbitrary privilege escalation.

Technologies: adm-zip (npm). Vendors: npm.

```
npm install adm-zip@0.6.1
```

Technical details

The vulnerability is a permission assignment flaw (CWE-732) in the fileAttr getter and extraction logic. When keepOriginalPermission=true, the library applies Unix mode bits directly from the ZIP entry header without masking out setuid (0o4000), setgid (0o2000), and sticky (0o1000) bits. An attacker-supplied ZIP can encode 0o4755 in the external file attributes; extraction as root creates a setuid binary that gains root privileges when executed by an unprivileged user. The fix is a one-line change to mask fileAttr with 0o777 instead of 0xfff.
