How Denial of Service via ZIP Parsing happens in Node.js and how to fix it

CVE-2026-39244 is a high-severity Denial of Service vulnerability in the adm-zip npm package (versions prior to 0.6.0) that allows an attacker to cause excessive memory allocation by supplying a specially crafted ZIP file. The fix upgrades adm-zip from 0.5.16 to 0.6.0 and pins the version via a package.json override to ensure no transitive dependency can silently pull in the vulnerable release. Left unpatched, any Node.js application that processes user-supplied ZIP archives with adm-zip is expo

How Denial of Service via ZIP Parsing happens in Node.js and how to fix it

CVE-2026-39244 is a high-severity Denial of Service vulnerability in adm-zip versions prior to 0.6.0, where a specially crafted ZIP file can cause the library to allocate excessive amounts of memory, potentially crashing the Node.js process. The fix involves upgrading adm-zip from 0.5.17 to 0.6.0 in the client-side dependency tree, patching the unsafe memory allocation behavior introduced by malicious ZIP metadata. Any application that processes user-supplied ZIP files using adm-zip is directly
