Summary
CVE-2026-70745 is a critical, easily exploitable vulnerability in Oracle Hyperion Financial Reporting that allows an unauthenticated attacker with network access via HTTP to fully compromise the affected system. Successful exploitation results in complete loss of confidentiality, integrity, and availability, meaning an attacker could read, modify, or destroy data and disrupt service without needing any credentials or user interaction. The flaw carries a CVSS v3.1 base score of 9.8 (Critical).
Technical details
- Root cause: A remotely reachable weakness in the Hyperion Financial Reporting server component that permits an attacker to compromise the product without prior authentication.
- Trigger conditions: The vulnerability is reachable over the network via the HTTP protocol used by the Financial Reporting server; no valid credentials or victim interaction are required to trigger it.
- Attack vector: Network (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N) — consistent with a straightforward, remotely exploitable path.
- Impact: Oracle’s own scoring reflects a "complete takeover" scenario — high impact to confidentiality, integrity, and availability (C:H/I:H/A:H), meaning a successful attacker gains full control over the affected Hyperion Financial Reporting deployment.
Affected software
- Oracle Hyperion Financial Reporting, version 11.2.25.0.000
Severity
- CVSS v3.1 Base Score: 9.8 (Critical)
- Vector:
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Mitigation and recommended actions
- Immediate: Apply the fixes provided in Oracle’s August 2026 Critical Security Patch Update (CSPU) for Oracle Hyperion Financial Reporting and related Hyperion Infrastructure Technology components. Organizations should update to the patched release identified in Oracle’s advisory as soon as possible, since Oracle rates this issue as remotely exploitable without authentication.
- If immediate patching is not possible: Restrict network access to the Hyperion Financial Reporting HTTP service to trusted internal networks only (e.g., via firewall rules, VPN, or network segmentation), and avoid exposing the Financial Reporting web interface directly to the internet until the patch is applied.
- General hardening: Monitor Hyperion Financial Reporting server logs for anomalous unauthenticated requests, and review Oracle’s advisory for any product-specific configuration or interim workaround guidance published alongside the patch.
