[parmarmanojkumar]

🚨 CRITICAL SECURITY VULNERABILITY

Severity: Critical
Component: Authentication Module
File: responsible-ai-moderationlayer/src/auth.py - Line 56

Issue Description

Bearer tokens are being logged in plaintext, creating a severe security risk.

Vulnerable Code

log.info(f"Bearer Token: {bearer_token}")  # Line 56

Security Impact

• Token exposure in log files
• Unauthorized access if logs are compromised
• Violation of secure token handling practices
• OWASP Top 10: A09 Security Logging and Monitoring Failures

Attack Scenario

1. Attacker gains access to log files
2. Extracts valid bearer tokens
3. Uses tokens to impersonate legitimate users
4. Gains unauthorized access to system

Recommended Fix

# Replace dangerous logging with:
log.info("Bearer token successfully obtained")
# NEVER log actual token values

Compliance Requirements

• SOC 2: Access logging and monitoring
• ISO 27001: Information security management
• OWASP ASVS: Authentication verification

Priority

• Impact: High (Authentication bypass possible)
• Likelihood: High (Logs commonly accessed)
• Risk Rating: Critical

Security Standards Violated

• NIST Cybersecurity Framework
• OWASP Authentication Security
• CIS Controls v8

This vulnerability must be fixed immediately before any production deployment.
