Security Vulnerability Fix

Issue: SnakeYAML Denial of Service Vulnerability
CVE: CVE-2022-25857
Severity: High
Fixed by: Ana Security Bot

🔍 Vulnerability Details

The org.yaml:snakeyaml package before version 1.31 is vulnerable to Denial of Service (DoS) attacks due to missing nested depth limitation for collections. This allows attackers to create deeply nested YAML structures that consume excessive system resources when parsed.

🛠️ Changes Made

• ✅ Updated org.yaml:snakeyaml from version 1.23 to 1.31
• ✅ Implemented nested depth limitations for YAML collections
• ✅ Updated dependency configurations in pom.xml
• ✅ Updated LICENSE file with new dependency information

📁 Files Modified

• pom.xml - Updated dependency version
• LICENSE - Updated dependency information

🔒 Security Impact

• Before: Application vulnerable to DoS attacks via deeply nested YAML
• After: YAML parsing protected with proper depth limitations
• Risk Reduction: Prevents resource exhaustion attacks

🧪 Testing Recommendations

• Test YAML parsing with deeply nested structures
• Verify application handles malformed YAML gracefully
• Confirm no regression in existing YAML functionality
• Load test with various YAML complexity levels
• Run security scans to validate fix

⚠️ Potential Impact

This update may affect YAML parsing behavior for deeply nested structures. Please test thoroughly in staging environment before deploying to production.
