CVE-2026-70766Network attack vector

Unauthorized data modification and disclosure

Published Aug 18, 2026 · Updated Aug 18, 2026

Improper access control in Oracle Hyperion Financial Reporting 11.2.25.0.000 allows remote attackers to read and modify data via HTTP. Oracle has not published the vulnerable endpoint or the specific server-side check that fails, so the precise mechanism remains undisclosed. Exploitation is network-reachable without credentials but requires human interaction from another person, and the stated impact is limited to partial read and write access rather than full takeover.
