What this page helps you understand
IDOR testing needs more than a 200 response. Fixnx reports ID mutation as likely unless separate user contexts prove that one user accessed another user's object.
What Fixnx checks
ID-based URLs
Object mutation
Session-aware probes
Ownership markers
UserA/UserB proof
Response comparison
A real IDOR finding needs ownership proof
Changing an ID and receiving 200 is a signal, not proof. The response might be public, empty, or scoped correctly.
Fixnx keeps that distinction visible. Confirmed IDOR requires evidence that one user accessed data owned by another user.
For best results, provide userA and userB sessions so the scanner can compare ownership boundaries.

FAQ
Why was my IDOR finding likely instead of confirmed?
Because the scan observed successful ID mutation but did not prove cross-user ownership exposure.
How do I confirm IDOR?
Provide two separate authenticated user contexts so the scanner can test user-owned resources across accounts.
