CVE-2025-63706Public exploitNetwork attack vector

Arbitrary command execution via unsanitized package name

Published May 7, 2026 · Updated May 7, 2026

Command injection in @jswork/next-npm-version 1.0.1 allows remote attackers to execute arbitrary OS commands through package-name input. The nx.npmVersion function inserts its inName argument into an npm show command and passes the string to child_process.execSync without neutralizing shell metacharacters. Exploitation requires a consuming application to pass attacker-controlled input to nx.npmVersion; injected commands run with the Node.js process privileges.
