CVE-2026-114102— adm-zip before 0.6.1 Denial of Service via inflateAsync Unhandled Error Event

Quick assessment

Affected
cthackers adm-zip
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

0.6.1 之前的 adm-zip 存在一个拒绝服务漏洞。由于 methods/inflater.js 中的 inflateAsync 方法缺少 zlib 流错误监听器，未认证的攻击者可通过构造畸形的 ZIP 文件导致 Node.js 进程崩溃。攻击者可提供包含损坏 DEFLATE 数据的 ZIP 文件，当该文件被 readFileAsync、readAsTextAsync、extractAllToAsync 或 getDataAsync 处理时，会触发无法捕获的异常，进而终止所有正在进行的请求。

Vulnerability Title
adm-zip before 0.6.1 Denial of Service via inflateAsync Unhandled Error Event
Source: CVE Program / CVE List V5
Vulnerability Description
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.
