Common Failure Conditions
Where technical controls break down.
Broken Object-Level Authorization
Users accessing resources that belong to other users. The most common and most exploited API vulnerability class.
Misconfigured Authentication
Weak token handling, missing session expiry, inconsistent auth across endpoints. Attackers look for these first.
Missing Rate Limiting
Sensitive endpoints exposed without throttling. Enables brute-force attacks, credential stuffing, and data enumeration.
Mass Assignment
API endpoints that accept more parameters than intended. Users modifying roles, permissions, or billing attributes.
Undiscovered Endpoints
Shadow APIs, legacy versions, debug endpoints still in production. Not inventoried, not tested, not secured.
Technical Assessment
Start with your technical surface.
If you have APIs in production that have not been tested adversarially, that is the place to begin.
