Testing for Insecure Direct Object References (IDOR)
Insecure Direct Object References (IDOR) occur when an application uses user-supplied input to access objects directly without proper authorization checks. Attackers can modify parameters like IDs, filenames, or keys to access unauthorized resources belonging to other users. IDOR is a form of broken access control and can lead to unauthorized data disclosure, modification, or deletion.
