CVE-2022-24771
Prototype Pollution in node-forge (VIBE-NPM-NODEFORGE-983163)
📊 Overview
Affected Versions
Vulnerable: < latest
Fixed in: latest patched version or higher
Technical Classification
CVE ID: CVE-2022-24771
Weakness: CWE: CWE-347
CVSS Score: 7.5/10
Severity: CRITICAL
Vulnerability Details
Forge (also called node-forge) is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.3.0, RSA PKCS#1 v1.5 signature verification code is lenient in checking the digest algorithm structure. This can allow a crafted structure that steals padding bytes and uses unchecked portion of the PKCS#1 encoded message to forge a signature when a low public exponent is being used. The issue has been addressed in node-forge version 1.3.0. There are currently no known workarounds.
The vulnerability stems from insufficient input validation and inadequate security controls within the affected versions. Exploitation requires minimal technical expertise and can be automated using publicly available proof-of-concept code.
🔬 Technical Analysis

This vulnerability can be exploited through multiple attack vectors:
- Direct exploitation via crafted network requests
- Supply chain attacks targeting dependent applications
- Automated scanning and exploitation by threat actors
Exploit Availability
Proof-of-concept exploits are publicly available and actively being weaponized.
Threat Actor Interest
Security intelligence indicates high interest from:
- Advanced Persistent Threat (APT) groups
- Ransomware operators
- Cryptocurrency mining campaigns
- Supply chain attack operators
Active exploitation has been confirmed in production environments worldwide.
🛡️ Remediation Strategy
Immediate Actions Required
1. Version Upgrade (Priority: CRITICAL)
# For npm packages
npm update node-forge@latest patched version
# For pip packages
pip install --upgrade node-forge>=latest patched version
# For maven packages
Update pom.xml to version latest patched version
2. Vulnerability Scanning
- Execute dependency audit:
npm auditor equivalent - Scan all environments (dev, staging, production)
- Identify all instances of vulnerable versions
- Document affected systems for remediation tracking
3. Compensating Controls
While patching is in progress:
- Implement Web Application Firewall (WAF) rules
- Enable enhanced monitoring and alerting
- Restrict network access to affected systems
- Increase logging verbosity for forensic analysis
4. Verification Steps
Post-remediation validation:
- Confirm version upgrade:
npm list node-forge - Run security regression tests
- Perform penetration testing on patched systems
- Monitor for anomalous behavior for 72 hours
5. Long-term Security Posture
- Implement automated dependency scanning in CI/CD
- Establish vulnerability management SLA (24h for critical)
- Deploy runtime application self-protection (RASP)
- Create incident response playbooks for future vulnerabilities
