CVE-2025-54313Known exploitationNetwork attack vector

Malware execution via malicious install script

Published Jul 19, 2025 · Updated Feb 26, 2026

Embedded malicious code in eslint-config-prettier 8.10.1, 9.1.1, 10.1.6, and 10.1.7 allows attackers to execute malware on Windows. The package adds install.js as an npm lifecycle script, which launches the bundled node-gyp.dll payload during installation. Installing an affected release with lifecycle scripts enabled is the gate, and the DLL runs in the installer account context.
