Security Vulnerability Exposed: How Poor API Design Compromises Court Records Systems

A significant security vulnerability has been discovered in Virginia’s Secure Circuit Court Remote Access system, revealing how poor API design can lead to unauthorized access of supposedly protected information.

The investigation uncovered that the court records system, which normally charges users approximately $50 per month for access, exposes authentication tokens in a way that allows anyone to bypass the login requirements entirely.

The Authentication Vulnerability

When analyzing network traffic on the Virginia court records website, we observed that simply visiting the “Available Courts” section triggers an authentication check that returns user status information. More concerning, the system readily provides access tokens, refresh tokens, and expiration information to users.

The tokens are implemented as JSON Web Tokens (JWT), a common authentication method, but the implementation contains a critical flaw: the system exposes username and password information directly in the token payload.

Exploiting the Vulnerability

With the exposed access token, unauthorized users can make API requests directly to the system without proper authentication. This includes accessing sensitive endpoints like “get instrument details for land records” simply by including the token in API requests.

The vulnerability was confirmed by testing access to the Lynchburg City Court website, which should require authentication but became fully accessible once the token was obtained.

Implications for API Security

This case highlights several critical lessons for developers and organizations:

  • Authentication tokens should never contain sensitive credentials
  • API designs must enforce proper authentication verification at every endpoint
  • Systems handling public records require particularly robust security measures
  • JWT implementations need careful review to prevent information leakage

As organizations increasingly rely on APIs for data access, this example serves as a cautionary tale about the importance of security-first design principles. Even paid services with seemingly secure infrastructure can contain fundamental flaws that compromise their entire security model.
