Modern APIs are riddled with complex business logic vulnerabilities like IDORs and access control issues.
For security engineers, these vulnerabilities are some of the most daunting—they can lead to data leaks and compliance failures with far-reaching consequences.
But here’s the challenge:
- Traditional tools struggle to catch them.
- Manual testing? Too slow and error-prone.
- Legacy DAST tools? They barely scratch the surface.
Think about it: attackers only need one missed access control flaw to exploit critical data. So how do we keep up with the growing complexity of APIs while ensuring comprehensive security testing?
One approach we explored builds on the concept of Feedback-Driven Semantic API Exploration (FDSAE), introduced by Marina Polishchuk from Microsoft (REST-ler)
Here’s what this method enables:
✅ It autonomously generates legitimate API traffic to mimic real-world application behavior.
✅ It transforms diverse API schemas (REST, GraphQL) into a unified MetaGraph for deeper analysis.
✅ It helps to integrate business logic testing seamlessly into CI/CD pipelines, catching IDORs before production.
The result? Smarter coverage, deeper insights, and real protection against vulnerabilities that matter most.
