Oracle Hyperion Financial Management Unauthenticated Remote Compromise (CVE-2026-87223)
First seen Sep 18, 2026 · Updated Sep 18, 2026 · CVSS 9.1
A critical, easily exploitable vulnerability in Oracle Hyperion Financial Management's Security component allows unauthenticated attackers with network access to compromise data integrity and availability. Successful exploitation can lead to unauthorized creation, deletion, or modification of financial data as well as denial-of-service conditions. Organizations running the affected version 11.2.26.0.000 should treat this as an urgent patching priority.
Technical Analysis
CVE-2026-87223 affects the Security component of Oracle Hyperion Financial Management version 11.2.26.0.000, with a CVSS 3.1 base score of 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H). The vulnerability is remotely exploitable over HTTP without authentication or user interaction, and low attack complexity makes it easily weaponizable. Impact is limited to Integrity and Availability (no confidentiality impact per the vector), meaning attackers can tamper with financial records or crash the application, but cannot directly exfiltrate data through this specific flaw. This is a traditional enterprise financial software vulnerability with no direct AI agent or LLM pipeline exposure; however, if AI agents are integrated into financial reporting or ERP automation workflows that call into Hyperion via API or scheduled tasks, a DoS or data-integrity compromise could corrupt data consumed by downstream agent-driven analytics or decision processes.
Affected Systems
