Summary
CVE-2026-70730 is a critical, easily exploitable vulnerability in the Deployment component of Oracle Hyperion Profitability and Cost Management. It allows a completely unauthenticated, remote attacker with only network access via HTTP to compromise the system, resulting in unauthorized creation, deletion, or modification of critical data as well as unauthorized access to all data within the affected system. The flaw carries a CVSS v3.1 base score of 9.1 (Critical), reflecting the combination of no required privileges, no user interaction, and high confidentiality/integrity impact.
Technical details
- Root cause: A flaw in the Deployment component of Oracle Hyperion Profitability and Cost Management that fails to properly enforce access controls, permitting unauthorized manipulation of application data.
- Trigger conditions: The vulnerability is reachable over HTTP without any authentication, making it exploitable by any attacker with network access to the affected deployment.
- Attack vector: Network (AV:N), with low attack complexity (AC:L) and no privileges (PR:N) or user interaction (UI:N) required — meeting the profile of an "easily exploitable" vulnerability per Oracle’s own classification.
- Impact: High confidentiality impact (unauthorized access to all accessible data) and high integrity impact (unauthorized creation, deletion, or modification of critical data). Availability is not impacted (A:N).
Affected software
- Oracle Hyperion Profitability and Cost Management, version 11.2.25.0.000
Severity
- CVSS v3.1 Base Score: 9.1 (Critical)
- Vector:
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
Mitigation and recommended actions
- Immediate: Apply the fix provided in Oracle’s August 2026 Critical Patch Update / Security Alert for Oracle Hyperion Profitability and Cost Management. Organizations should update to the version designated as patched in the Oracle advisory as soon as possible, per standard Oracle CPU guidance.
- If immediate patching is not possible: Restrict network access to the Hyperion Profitability and Cost Management deployment to trusted internal networks only, and place it behind authentication-enforcing network controls (e.g., VPN, reverse proxy with authentication) until the patch can be applied, since the vulnerability is remotely exploitable over HTTP without credentials.
- Monitor exposed Oracle Hyperion instances for unusual data modification or access patterns as an interim detective control.
