AI risk analysis
- Summary
- The vulnerability allows attackers to bypass authentication by forging admin session tokens using a hardcoded HMAC secret, enabling full administrative access to protected API routes including the Doris SQL query API.
- Exploitability
- Very easy to exploit with no prerequisites - attackers only need to know the service is running and can make requests to forge valid admin tokens using the default dev-secret.
- Blast radius
- High impact across all systems using this component, potentially allowing full database access and administrative control over protected API endpoints.
- Detection
- Monitor for unauthorized access attempts to /webapi routes with admin privileges, particularly those involving JWT tokens signed with the default dev-secret signature.
- Prioritized remediation
- Upgrade to version 0.1.11 or later to fix the hardcoded HMAC secret issue in JwtTokenService.
