CVE-2026-83002 · Severity: high · CVSS 8.5 · Published 2026-09-15

Oracle Access Manager is an identity and access control system used to authenticate users and control access to enterprise applications. A vulnerability in its authentication engine allows a low-privileged attacker with network access to completely take over the system, potentially compromising confidentiality, integrity, and availability of protected applications and data. The attack requires difficult exploitation conditions but can impact other connected systems beyond Access Manager itself.
