🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Not available

Vendor Advisory: Not available

Restart Required: No

Instructions:

No official patch available. Monitor the GitHub repository for updates: https://github.com/birkir/prime/issues/545

🔧 Temporary Workarounds

Implement GraphQL Query Depth Limiting

all

Limit the maximum depth of GraphQL queries to prevent resource exhaustion attacks.

# Implementation depends on your GraphQL server setup. For Apollo Server: depthLimit(10)

Implement Rate Limiting

all

Add rate limiting to the /graphql endpoint to prevent abuse.

# Use middleware like express-rate-limit for Node.js applications

🧯 If You Can't Patch

  • Block or restrict access to the /graphql endpoint using network controls or WAF rules.
  • Monitor server resource usage (CPU, memory) and set up alerts for abnormal consumption patterns.

🔍 How to Verify

Check if Vulnerable:

Check if running birkir prime version 0.4.0.beta.0 or earlier with GraphQL endpoint enabled.

Check Version:

Check package.json or application configuration for birkir prime version.

Verify Fix Applied:

Verify version is later than 0.4.0.beta.0 once patch is available.

📡 Detection & Monitoring

Log Indicators:

  • Unusually large or complex GraphQL queries
  • Spike in CPU/memory usage from GraphQL processes
  • Multiple rapid requests to /graphql endpoint

Network Indicators:

  • High volume of POST requests to /graphql
  • Large payloads sent to GraphQL endpoint

SIEM Query:

source="application_logs" AND (uri_path="/graphql" AND (request_size>10000 OR request_count>100 per minute))
