Overview

Affected versions of this package are vulnerable to Improper Check for Unusual or Exceptional Conditions through improper handling of error conditions in the PatchIndividualApplicationPFDManagement process. An attacker can cause the application to panic and return a 500 Internal Server Error by sending a crafted PATCH request to the affected endpoint when upstream UDR access is failing, leading to a nil pointer dereference. This is only exploitable if the UDR service is unreachable or experiencing failures, and the NEF route is accessible without authentication.
