Summary

CVE-2026-70749 is a high-severity vulnerability in the Server component of Oracle Hyperion Financial Reporting that allows an unauthenticated, remote attacker with network access via HTTP to compromise the application. Oracle’s own advisory language classifies this as "difficult to exploit," but warns that successful exploitation "can result in takeover of Oracle Hyperion Financial Reporting" — impacting confidentiality, integrity, and availability. The vulnerability was published as part of Oracle’s Critical Security Patch Update (CSPU) released on August 18, 2026.

Technical details

  • Root cause: Oracle has not published a detailed root-cause description or CWE classification in the public CVE record; the vendor advisory characterizes it only as a flaw in the Server component of the product.
  • Trigger conditions: The vulnerability is reachable over HTTP without any authentication and does not require user interaction, but Oracle rates the attack complexity as High (AC:H), indicating exploitation requires specific conditions or non-trivial attacker effort to succeed reliably.
  • Attack vector: Network-based (AV:N) — no local access, credentials, or victim interaction are required for an attacker to reach the vulnerable component.
  • Impact: Successful exploitation results in complete takeover of the affected Hyperion Financial Reporting instance, with full compromise of confidentiality, integrity, and availability (C:H/I:H/A:H).

Affected software

  • Oracle Hyperion Financial Reporting — version 11.2.25.0.000 (Server component)

Severity

  • CVSS v3.1 Base Score: 8.1 (High)
  • Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Apply the fix provided in Oracle’s Critical Security Patch Update dated August 18, 2026, which addresses CVE-2026-70749 for Oracle Hyperion Financial Reporting 11.2.25.0.000. Organizations should consult Oracle’s advisory directly for the specific patch identifier applicable to their environment and apply it as soon as possible given the network-exploitable, unauthenticated nature of the flaw.
  • If immediate patching is not possible: Restrict network exposure of Hyperion Financial Reporting management and application interfaces — do not expose the service directly to the internet, and limit HTTP access to trusted internal networks or via a VPN/reverse proxy with strict access controls. Monitor HTTP access logs for anomalous or unauthenticated requests to the Financial Reporting server component until the patch can be applied.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
