This vulnerability resides in the Security component of Oracle Hyperion Financial Management, a critical application used for financial consolidation and reporting. The flaw allows an unauthenticated attacker, who already has local access to the infrastructure where the application executes, to compromise the system’s confidentiality. The core issue is insufficient access control or improper input validation within the application’s security layer, which fails to adequately restrict data access when certain internal processes are invoked locally.
The attack requires logon to the host system, meaning the attacker must have shell or terminal access to the server, either through a compromised service account, a malicious insider, or by chaining this vulnerability with another remote code execution flaw. Once authenticated at the operating system level, the attacker can execute a specific sequence of commands or interact with a local service that exposes sensitive data without requiring further authentication to the application itself. The vulnerability is classified as “Easily exploitable” because it does not require complex prerequisites beyond local access, and the attack complexity is low, meaning the steps to trigger the issue are straightforward. The impact is limited to reading a subset of the accessible data, which may include financial reports, user details, or configuration files, but does not allow modification, deletion, or privilege escalation within the application. The CVSS 3.1 score is 4.0, reflecting a Moderate severity due to the limited confidentiality impact and the local access requirement. The CVSS vector highlights that the attack vector is Local (AV:L), attack complexity is Low (AC:L), and no privileges (PR:N) or user interaction (UI:N) is needed, with an Unchanged (S:U) scope. This issue affects version 11.2.25.0.000, and organizations running this version are at risk if local access is not tightly controlled. Oracle has published a security advisory referencing this CVE, urging customers to apply the forthcoming patch to mitigate the risk.
DailyCVE Form:
Platform: Oracle Hyperion
Version: 11.2.25.0.000
Vulnerability: Info Disclosure
Severity: Medium
date: 08/18/2026
Prediction: October 2026
What Undercode Say:
Analytics shows this CVE is trivial to exploit given local access. Attackers will target misconfigured servers.
Check if vulnerable Hyperion service is running ps aux | grep hyperion Test local access to sensitive endpoint curl --unix-socket /tmp/hyperion.sock http://localhost/internal/data
Exploit: (Educational Purposes!)
Enumerate local services netstat -tulpn | grep 8080 Interact with the insecure local API wget --header="Host: localhost" http://127.0.0.1:8080/api/v1/financial/reports
Protection:
Restrict local logon to trusted administrators, enable host-based firewalls, apply vendor patches, and monitor local access logs.
Impact:
Unauthorized read of financial data, potentially exposing sensitive corporate financials, leading to regulatory fines and reputational damage.
