CVE-2026-70887Network attack vector

Unauthenticated data access and modification

Published Aug 18, 2026 · Updated Aug 18, 2026

Access control flaw in Oracle Hyperion Data Relationship Management 11.2.25.0.000 allows remote attackers to read and modify data via HTTP. Oracle has disclosed only that the bug is in the Access and security component and has not published the affected endpoint, code path, or the incorrect trust check on HTTP requests. No authentication or user interaction is required, so any internet- or intranet-reachable 11.2.25.0.000 instance should be triaged as exposed to unauthorized data disclosure and limited data tampering.
