Lifecycle Timeline
2DescriptionCVE.org
Vulnerability in the Oracle Hyperion Calculation Manager product of Oracle Hyperion (component: Security). The supported version that is affected is 11.2.25.0.000. Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Hyperion Calculation Manager. While the vulnerability is in Oracle Hyperion Calculation Manager, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Hyperion Calculation Manager accessible data as well as unauthorized access to critical data or complete access to all Oracle Hyperion Calculation Manager accessible data. CVSS 3.1 Base Score 9.6 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N).
AnalysisAI
Privilege abuse and cross-product compromise in Oracle Hyperion Calculation Manager 11.2.25.0.000 lets an attacker holding only low-level network credentials read and tamper with all data the product can reach, and - because of a scope change - pivot to significantly impact additional Oracle Hyperion components beyond Calculation Manager. Oracle rates it CVSS 3.1 9.6 with high confidentiality and integrity impact but no availability impact, and the vendor tags it as an authentication-bypass-class flaw in the Security component. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network access to the Oracle Hyperion Calculation Manager HTTP interface plus a low-privileged authenticated account (CVSS PR:L), and no user interaction is needed (UI:N) with low attack complexity (AC:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals here are strong on impact but incomplete on exploitation telemetry. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the fixes delivered in Oracle's August 2026 Critical Patch Update, which is the advisory covering this CVE (https://www.oracle.com/security-alerts/cspuaug2026.html); patch available per vendor advisory, though the source data does not state a discrete fixed build number beyond the CPU, so confirm the exact patch/PSU level for 11.2.25.0.000 directly from the Oracle advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify all systems running Hyperion Calculation Manager version 11.2.25.0.000; implement network-level access restrictions and segmentation to limit who can reach this component; audit access logs from the past 90 days for suspicious activity. …
