CVE-2026-23598
Unauthenticated Information Disclosure in application API allows sensitive system information exposure
Description
Vulnerabilities in the API error handling of an HPE Aruba Networking 5G Core server API could allow an unauthenticated remote attacker to obtain sensitive information. Successful exploitation could allow an attacker to access details such as user accounts, roles, and system configuration, as well as to gain insight into internal services and workflows, increasing the risk of unauthorized access and elevated privileges when combined with other vulnerabilities.
