insecure direct object reference

Insecure direct object references (IDOR) are a type of access control vulnerability that arises when an application uses user-supplied input to access objects directly. Identifying the client-side surface attack As OWASPs description, Beyond just the data in a database, an attacker can exploit it to access restricted files or directories on the server. This prevents attackers from directly targeting unauthorized resources. Prevalence Insecure direct object references (IDOR) are a cybersecurity issue that occurs when a web application developer uses an identifier for direct access to an internal implementation object but provides no additional access control and/or authorization checks. But, using this type of access control attack, skilled hackers/threat actors can create a threat-conducive environment for a bigger and damage-causing attack.
