TL;DR: Traditional scanners can miss broken access control, IDOR, and authorization bypass because those flaws have no payload or signature to match, according to Gecko Security. Semantic code analysis is now the dividing line between surface-level findings and tools that can reason across service boundaries and code intent.

By the numbers:
- Gecko Security reported 50% fewer false positives than traditional tools when validating semantic findings with proof-of-concept exploits.
Questions worth separating out
Q: What breaks when pattern-based scanners are used to find authorization flaws?
A: They miss defects that do not have a recognizable signature, including missing permission checks, IDOR, and privilege escalation paths.
Q: Why do broken access control bugs matter to IAM teams?
A: Because the application is often making the last authorization decision.
Q: How do security teams know whether dynamic authorization is working?
A: Look for fewer persistent credentials, shorter token lifetimes, and audit records that show workload identity, resource, policy outcome and context for each request.
Practitioner guidance
- Adopt semantic testing for authorization logic Add testing methods that can reason about access control intent across APIs, service meshes, and backend calls.
- Map cross-service trust boundaries Document where authentication ends and authorization begins across gateways, microservices, and data services.
- Require exploit validation for high-risk findings Treat business logic alerts as unconfirmed until a proof-of-concept shows the path is real.

Broken access control is now an identity governance problem as much as an appsec problem. When application code decides whether a principal can act, authorization has become part of the identity plane even if the tooling sits in a developer workflow. That means IAM, PAM, and appsec teams are looking at the same failure from different angles. The practical conclusion is that authorisation logic must be governed as a security control, not treated as a purely engineering concern.
A question worth separating out:
Q: Should organisations combine SAST with semantic application testing?
A: Yes, because they solve different problems. SAST is still useful for syntactic issues and known vulnerability patterns, while semantic testing targets intent failures like broken access control. Most teams need both if they want coverage across injection, business logic, and distributed authorization paths.
