Oracle Hyperion CVE-2026-62538

The vulnerability requires HTTPS network access to the Oracle Hyperion Infrastructure Technology Installation and Configuration component on version 11.2.25.0.000. The CVSS vector (PR:N, UI:N) confirms that exploitation does not require valid credentials or any action from a victim user. However, the AC:H rating is a meaningful constraint: exploitation is not straightforward and requires meeting specific technical conditions - possibly involving particular request structures, protocol states, or the deployment phase of the installation and configuration subsystem (for example, an active or recently completed setup workflow). These conditions limit opportunistic or automated exploitation but do not prevent a targeted, technically capable attacker. Exploitation is further bounded by scope unchanged (S:U), meaning the attacker cannot pivot laterally to systems outside Hyperion's trust boundary from this vulnerability alone. There is no availability impact, ruling out denial-of-service use cases. Non-default or specialized configuration requirements are not described in available sources beyond the component and version specificity.

The CVSS 3.1 score of 7.4 (High) reflects a meaningful threat: network-accessible, requiring no credentials, with high impacts on both confidentiality and integrity. However, the AC:H rating is a genuine risk moderator - exploitation is rated difficult, meaning automated, opportunistic campaigns are unlikely to succeed reliably, and a motivated attacker must invest in understanding the specific preconditions. EPSS data is absent from available intelligence, preventing probabilistic exploitation rate forecasting, which is a gap worth noting. No CISA KEV listing and no public exploit code have been observed, suggesting this has not entered active mass exploitation at time of analysis. That said, even a mid-sized municipal IT team in swidnica running Oracle Hyperion for financial consolidation should treat this as a priority patching item, given that financial EPM systems hold sensitive budget, forecast, audit, and consolidation data whose unauthorized disclosure or modification carries serious business and regulatory consequences. The absence of availability impact (A:N) means the risk is confidentiality and integrity focused - data theft and silent data manipulation are the primary threat models, not disruption. Overall: real priority for Hyperion operators, but the AC:H rating distinguishes this from a spray-and-pray exploit scenario.

A remote attacker with HTTPS connectivity to the Oracle Hyperion Infrastructure Technology installation and configuration endpoint crafts a specially formed request that satisfies the specific technical preconditions required to bypass authentication controls - possibly exploiting a missing or improperly enforced authentication check in the setup subsystem. Once the bypass succeeds, the attacker can enumerate, exfiltrate, or alter all financial planning and consolidation data accessible within the Hyperion environment, including sensitive budget forecasts, audit records, and consolidation hierarchies. No public proof-of-concept code has been identified at time of analysis, and the AC:H rating indicates this is not a trivially repeatable attack, requiring targeted effort rather than automated tooling.
