CVE-2026-70785 Overview
CVE-2026-70785 is an information disclosure vulnerability in the Oracle Hyperion Financial Reporting product of Oracle Hyperion. The flaw resides in the Server component and affects supported version 11.2.25.0.000. An unauthenticated remote attacker with network access via HTTP can exploit this weakness to gain unauthorized read access to a subset of Oracle Hyperion Financial Reporting data. Oracle rates the issue as difficult to exploit, and its impact is limited to confidentiality. The vulnerability was published to the National Vulnerability Database (NVD) on August 18, 2026.
Critical Impact
Successful exploitation grants an unauthenticated attacker unauthorized read access to a subset of data stored in Oracle Hyperion Financial Reporting, exposing sensitive financial information.
Affected Products
- Oracle Hyperion Financial Reporting 11.2.25.0.000
- Oracle Hyperion (Server component)
- Deployments exposing the Hyperion HTTP interface to untrusted networks

Technical Details for CVE-2026-70785
Vulnerability Analysis
CVE-2026-70785 is an information disclosure issue in the Server component of Oracle Hyperion Financial Reporting. The vulnerability allows a network-based attacker to retrieve a subset of application data without authenticating. Oracle categorizes exploitation as difficult, indicating that special conditions or timing must be met to succeed. Impact is confined to confidentiality; integrity and availability of the target system remain unaffected.
Oracle's advisory does not disclose the underlying mechanism, but the vector confirms the flaw is reachable over HTTP without user interaction or prior credentials. Enterprises running Hyperion typically process financial planning, budgeting, and consolidation data, so even partial data exposure carries regulatory and business risk.
Root Cause
Oracle has not publicly disclosed the specific defect, and no Common Weakness Enumeration (CWE) identifier is currently assigned to CVE-2026-70785. Based on the vector and impact profile, the root cause is an access control or information exposure weakness in an HTTP-facing Hyperion Server endpoint that returns application data without properly enforcing authentication or authorization.
Attack Vector
The attack vector is network-based over HTTP. An unauthenticated attacker sends crafted requests to the Hyperion Financial Reporting Server to trigger the disclosure. No user interaction is required. The high attack complexity indicates the request must satisfy specific preconditions to return data. Refer to the Oracle Security Alert for vendor-provided technical details.

Detection Methods for CVE-2026-70785
Indicators of Compromise
- Unauthenticated HTTP requests to Oracle Hyperion Financial Reporting Server endpoints originating from unexpected source addresses.
- HTTP responses returning financial report metadata or content to sessions that never completed authentication.
- Anomalous spikes in read-only requests against Hyperion reporting URLs outside normal business hours.
Detection Strategies
- Enable verbose HTTP access logging on the Hyperion Server and alert on request patterns targeting reporting endpoints without valid session cookies or tokens.
- Correlate web server logs with authentication logs to identify data-bearing responses that lack a preceding successful login event.
- Deploy web application firewall (WAF) rules that inspect for anomalous parameter combinations against Hyperion Financial Reporting URLs.
Monitoring Recommendations
- Baseline normal request volume and response sizes for Hyperion Financial Reporting endpoints, then alert on statistical deviations.
- Forward Hyperion application and web tier logs to a centralized analytics platform for retention and cross-source correlation.
- Track outbound data volumes from the Hyperion Server to detect bulk retrieval that may indicate exploitation.
How to Mitigate CVE-2026-70785
Immediate Actions Required
- Apply the fixes published in the Oracle Critical Patch Update referenced in the Oracle Security Alert.
- Inventory all Oracle Hyperion Financial Reporting deployments and confirm which run version 11.2.25.0.000.
- Restrict network reachability to the Hyperion Server so only trusted internal networks and VPN clients can reach the HTTP interface.
- Review web server access logs for prior unauthenticated requests to reporting endpoints and investigate any data-bearing responses.
Patch Information
Oracle addressed CVE-2026-70785 in the August 2026 Critical Patch Update cycle. Administrators should download and apply the patch bundle referenced in the Oracle Security Alert that corresponds to Oracle Hyperion Financial Reporting 11.2.25.0.000. Validate patch application in a non-production environment before rolling out to production Hyperion tiers.
Workarounds
- Place the Hyperion Financial Reporting Server behind an authenticating reverse proxy that terminates unauthenticated requests before they reach the application.
- Enforce IP allow-listing at the network edge to block Internet-sourced access to Hyperion HTTP endpoints.
- Disable or firewall any non-essential Hyperion services and endpoints that are not required for business operations.
# Example: restrict access to the Hyperion HTTP port to trusted subnets
iptables -A INPUT -p tcp --dport 19000 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 19000 -j DROP
