CVE-2026-35313 · Severity: critical · CVSS 9.9 · Published 2026-06-17

Oracle Access Manager, a critical tool used to manage user identities and control access to corporate applications, contains a severe security flaw in its authentication engine. A user with very basic access to the network can exploit this weakness to take full control of the system. Because this tool manages access for many other business applications, a successful attack could allow an unauthorized person to compromise multiple connected systems and sensitive data across the organization.
