Bola Idor with Api Keys

API Keys-Specific Remediation

Remediating BOLA/Idor in API key systems requires implementing proper authorization checks at the resource level. The solution involves verifying that the API key's owner has explicit permission to access the specific resource being requested.

The most effective approach is implementing row-level security (RLS) or resource-based authorization. Here's how to fix common API key BOLA patterns:

Frequently Asked Questions

How can I test my API for BOLA/Idor vulnerabilities?
Test by systematically manipulating resource identifiers in API requests. Use your valid API key to access different resource IDs than you own. If the API returns data instead of authorization errors (403/404), you have a BOLA vulnerability. middleBrick automates this testing by scanning your API endpoints and identifying parameter manipulation vulnerabilities across all 12 security categories, including BOLA/Idor.
What's the difference between authentication and authorization in API key systems?
Authentication verifies the API key is valid and identifies who is making the request. Authorization determines what resources that authenticated user can access. A common BOLA mistake is validating the API key (authentication) but not checking if the key's owner has rights to the specific resource being requested (authorization). Both steps are essential for secure API design.
