16INSECURE DIRECT OBJECT REFERENCES

Image

An insecure direct object reference (IDOR) vulnerability occurs when an attacker can access or modify a reference to an object, such as a file, database record, account, and so on, that should be inaccessible to them. For example, let’s say the website www.<example>.com has private user profiles that should be accessible only to the profile owner through the URL www.<example>.com/user?id=1. The id parameter would determine which profile you’re viewing. If you can access someone else’s profile by changing the id parameter to 2, that would be an IDOR vulnerability.
