CVE-2025-68619Public exploitNetwork attack vector

Authenticated code execution via unsanitized npm version specifier

Published Jan 1, 2026 · Updated Jan 1, 2026

Code injection in Signal K Server before 2.19.0 allows remote authenticated users to execute commands via a crafted npm version specifier. The app-store installation route passes its unvalidated version parameter into npm, which accepts attacker-controlled repositories or tarballs and runs their postinstall scripts. Administrative access is required, and successful exploitation executes code with the privileges of the Signal K Server process.
