CVE-2026-114105

The Adm-zip library, in versions prior to 0.6.1 , is vulnerable to an incorrect permission assignment flaw when the keepOriginalPermission option is enabled. An attacker can craft malicious ZIP files with external file attributes that are passed unmasked into the chmod function. This allows the a...

CVE-2026-102282 adm-zip extraction preserves SUID/SGID bits from untrusted ZIPs -> local privilege escalation

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...

CVE-2026-102282

The adm-zip Node.js library (prior to 0.6.1 ) contains a vulnerability where it preserves SUID , SGID , and sticky bits from untrusted ZIP archives when the keepOriginalPermission=true flag is enabled. Specifically, the fileAttr property in headers/entryHeader.js uses an incorrect bitmask (0xfff)...

adm-zip extraction preserves SUID/SGID bits from untrusted ZIPs -> local privilege escalation

Summary 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...
