Summary

adm-zip before 0.6.1 applies the Unix permission bits stored in ZIP entries when the keepOriginalPermission option is set, and it does not remove the setuid and setgid bits (CWE-732). A local user with low privileges can supply a crafted ZIP archive so that an extracted file carries the setuid bit. When extraction runs as root, a less privileged user who later runs that file gets root execution.

Description from the CNA

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.

Remediation

Update adm-zip to 0.6.1, which fixes both the npm package and the cthackers entry. Red Hat fixes it in Red Hat OpenShift AI 3.4 (RHSA-2026:92510) and Red Hat Ansible Automation Platform 2.2 (RHSA-2026:86675). The sources list no fixed version for Red Hat Build of Podman Desktop, Red Hat OpenShift Container Platform 4 and Red Hat OpenShift AI (RHOAI), and Red Hat Fuse 7 has no fix planned.
