SCA: security update for pnpm (GHSA-6pfh-p556-v868)
medium Tenable Self-Hosted Container Security Plugin ID 437336
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- 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. (CVE-2026-23888)
