AnalysisAI
Partial authentication bypass in Oracle Hyperion Calculation Manager 11.2.25.0.000 allows an unauthenticated remote attacker to read a limited subset of application data over HTTP without valid credentials. The attack is classified as difficult to exploit (AC:H), meaning specific conditions must be met for reliable success, and impact is confined to low-level confidentiality loss with no integrity or availability consequences. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires network-level HTTP access to an Oracle Hyperion Calculation Manager instance running specifically version 11.2.25.0.000. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 3.7 (Low) is a reasonable representation of real-world risk here: the attack vector is network-accessible (AV:N) and requires no authentication (PR:N) or user interaction (UI:N), but the high attack complexity (AC:H) is a meaningful limiter indicating that exploitation depends on conditions not reliably or consistently present - such as a race condition, specific server state, or timing window. … 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 | The primary remediation is to apply Oracle's Critical Patch Update for August 2026, available at https://www.oracle.com/security-alerts/cspuaug2026.html, which addresses this vulnerability in Hyperion Calculation Manager 11.2.25.0.000. … Detailed patch versions, workarounds, and compensating controls in full report. |
