PatchTheCVECVE-2026-114102: adm-zip before 0.6.1 contains a denial of service vulnerability that allows unauthenticated attackers to crash
CVE-2026-114102 is a high-severity flaw (CVSS 7.5) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
adm-zip before 0.6.1 contains a denial of service vulnerability that allows unauthenticated attackers to crash the Node.js process via a malformed ZIP file, because inflateAsync in methods/inflater.js lacks a zlib stream error listener. Attackers can supply a ZIP with corrupted DEFLATE data processed by readFileAsync, readAsTextAsync, extractAllToAsync, or getDataAsync, triggering an uncatchable exception that terminates all in-flight requests.
Why this priority
- High severity
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
