This vulnerability exists in the Common Events component of Oracle Hyperion Infrastructure Technology version 11.2.25.0.000. It is easily exploitable by unauthenticated attackers over the network via HTTP, enabling full compromise of the affected system. The CVSS 3.1 vector indicates network attack vector, low attack complexity, no privileges required, no user interaction, and impacts confidentiality, integrity, and availability at a high level. Oracle's advisory references a broad Critical Security Patch Update released in August 2026 addressing numerous vulnerabilities across many products, including Oracle Hyperion Infrastructure Technology, but does not explicitly state patch availability for this exact version.

Successful exploitation can lead to complete takeover of Oracle Hyperion Infrastructure Technology, impacting confidentiality, integrity, and availability of the system. This could allow attackers to execute arbitrary code, access sensitive data, and disrupt service operations.

Oracle strongly recommends applying security patches promptly and remaining on actively supported versions. The August 2026 Critical Security Patch Update advisory should be consulted for patch availability and installation instructions. Since the vendor advisory does not explicitly confirm patch availability for version 11.2.25.0.000, users should verify the latest Oracle patch documentation. No indication was given that the vulnerability is already mitigated or requires no action.
