CVE-2026-23888— pnpm 代码问题漏洞

pnpm: Binary ZIP extraction allows arbitrary file write via path traversal (Zip Slip)

pnpm is a package manager. Prior to version 10.28.1, a path traversal vulnerability in pnpm's binary fetcher allows malicious packages to write files outside the intended extraction directory. The vulnerability has two attack vectors: (1) Malicious ZIP entries containing `../` or absolute paths that escape the extraction root via AdmZip's `extractAllTo`, and (2) The `BinaryResolution.prefix` field is concatenated into the extraction path without validation, allowing a crafted prefix like `../../evil` to redirect extracted files outside `targetDir`. The issue impacts all pnpm users who install packages with binary assets, users who configure custom Node.js binary locations and CI/CD pipelines that auto-install binary dependencies. It can lead to overwriting config files, scripts, or other sensitive files leading to RCE. Version 10.28.1 contains a patch.

对路径名的限制不恰当(路径遍历)

pnpm 代码问题漏洞

pnpm是pnpm开源的一个包管理器。 pnpm 10.28.1之前版本存在代码问题漏洞，该漏洞源于二进制文件提取器存在路径遍历，可能导致恶意包在预期提取目录外写入文件。
