CVE-2026-87218

Unauthenticated data modification and service interruption

Published Sep 15, 2026 · Updated Sep 15, 2026

Improper access control in Oracle Hyperion Financial Management 11.2.26.0.000 allows remote attackers to modify data or interrupt service via TCP. Oracle has not published the flawed Security-component operation or the TCP input that reaches it. Exploitation requires access to the adjacent physical communication segment but no authentication; it permits critical-data creation, deletion, or modification and can hang or repeatedly crash the service.
