## Technical details

An Insecure Direct Object Reference (IDOR) vulnerability exists in Kiteworks Secure Data Forms prior to version 9.3.0. The flaw is caused by insufficient authorization checks on resource ownership when processing form submissions. A remote, authenticated attacker with low privileges can exploit this by modifying user-controlled keys (such as resource IDs) in network requests to add arbitrary submissions to forms belonging to other users. This is classified as an authorization bypass through a user-controlled key (CWE-639). The issue is resolved in Kiteworks version 9.3.0.
