2DescriptionCVE.org
Vulnerability in the Oracle Hyperion Infrastructure Technology product of Oracle Hyperion (component: Common Events). The supported version that is affected is 11.2.25.0.000. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Hyperion Infrastructure Technology. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Hyperion Infrastructure Technology, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Hyperion Infrastructure Technology accessible data as well as unauthorized update, insert or delete access to some of Oracle Hyperion Infrastructure Technology accessible data. CVSS 3.1 Base Score 8.2 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N).
AnalysisAI
The Common Events component of Oracle Hyperion Infrastructure Technology 11.2.25.0.000 exposes an unauthenticated network-accessible attack path requiring victim interaction, enabling complete unauthorized read access to all Hyperion-accessible data and limited write capability through a scope-changing exploit. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N) combined with the Authentication Bypass tag and scope change indicator is strongly consistent with a client-side injection flaw - such as reflected XSS or CSRF - in the Common Events interface that can hijack or bypass authenticated session controls. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires unauthenticated network access to the Oracle Hyperion Infrastructure Technology Common Events component over HTTP, and active human interaction from a victim - most plausibly an authenticated Hyperion user who clicks a malicious link or visits an attacker-controlled page that initiates the crafted request. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 8.2 (High) reflects a highly accessible attack - network-reachable, low complexity, no attacker privileges - tempered only by the UI:R requirement. … 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 Oracle's Critical Security Patch Update for August 2026, which addresses CVE-2026-62485 for Oracle Hyperion Infrastructure Technology. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify and inventory all systems running Oracle Hyperion Infrastructure Technology 11.2.25.0.000 and assess the sensitivity of data these systems can access; immediately implement network-level access restrictions limiting Hyperion Common Events interface exposure to essential users only. …
