Code Injection in npm (CVE-2025-63706)
Summary
code injection in npm (CVE-2025-63706). Successful exploitation can lead to full system takeover.
AI summary openai / gpt-4o
This vulnerability is found in the npm package "next-npm-version" version 1.0.1, which fails to properly validate input, allowing attackers to execute arbitrary commands. Similar vulnerabilities have led to internal server compromises in the past. If using the affected version, apply patches immediately and strengthen overall system security.
The npm package "next-npm-version" version 1.0.1 has a critical command injection vulnerability, particularly in the "nx.npmVersion" function. This function does not properly sanitize the "inName" parameter before passing it to "execSync", allowing an attacker to execute arbitrary commands. For instance, `nx.npmVersion('malicious && command #')` can be used to exploit this. The affected version is up to 1.0.1 with no patched version available yet. Detection can be done by monitoring logs for suspicious strings in all "npmVersion" function calls.
❓ What is the problem
Command injection in npm package next-npm-version due to improper input sanitization in function nx.npmVersion.
📍 Affected scope
In function nx.npmVersion, particularly when handling the inName parameter in index.js.
🔥 Severity
Critical, with a CVSS score of 9.8, allowing remote command execution without authentication or user interaction.
🔧 How to fix
Update the package once the patched version is available. Meanwhile, avoid using nx.npmVersion with unsanitized input.
🛡️ Workaround
Use input validation to ensure only expected values are passed to nx.npmVersion or avoid using the vulnerable function.
🔍 Detection
Monitor logs for unexpected commands being passed to nx.npmVersion or use security tools scanning for execSync misuse.
