Oracle Hyperion CVE-2026-62502

Exploitation requires a valid low-privileged account with HTTP network access to the Oracle Hyperion Infrastructure Technology 11.2.25.0.000 instance, as confirmed by CVSS metric PR:L. The attack targets the Common Events component over standard HTTP and requires no user interaction and no elevated credentials beyond a basic authenticated session. The 'Authentication Bypass' tag in the source intelligence suggests that a low-privileged principal may be able to circumvent authorization gates intended for higher-privilege operations within Common Events - meaning any user who can authenticate to Hyperion over HTTP may be able to reach functionality or data normally restricted to administrators or privileged roles. No non-default configuration is indicated as a prerequisite; standard deployments of the affected version appear exploitable. Exploitation is bounded by the requirement for at least minimal authenticated access: fully unauthenticated external attackers cannot exploit this without first obtaining Hyperion credentials.

The CVSS 3.1 base score of 8.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N) characterizes a low-complexity, network-exploitable flaw requiring only minimal authenticated access, placing it firmly in the urgent-remediation category for any organization running this product version - the combination of broad network reachability, trivial complexity, and dual high-impact outcomes (full confidentiality and integrity) means even a mid-sized municipal IT department in bytom operating Hyperion on an internal network should treat patching as a near-term priority rather than deferred maintenance. No EPSS score is present in the provided data, preventing numerical exploitation-probability quantification; the absence of a CISA KEV entry confirms no active exploitation has been formally reported, and no public proof-of-concept is identified. The 'Authentication Bypass' tag introduces a noteworthy tension: the CVSS PR:L metric implies low privilege is a genuine prerequisite, yet an authentication bypass component could indicate that those minimal credentials are sufficient to circumvent controls designed for higher-privilege operations - this discrepancy should be verified against Oracle's advisory detail. Availability is unaffected per the CVSS vector, which narrows the risk profile but does not reduce urgency given the critical data exposure and modification potential.

An attacker holding a low-privileged Hyperion account sends crafted HTTP requests to the Common Events component, exploiting insufficient authorization controls to escalate effective access beyond their privilege tier. Without needing any user interaction or additional credentials, the attacker retrieves or modifies critical financial or operational data across the full Oracle Hyperion Infrastructure Technology environment. No public exploit code is known at time of analysis, but the low attack complexity (AC:L) and straightforward HTTP attack vector indicate the vulnerability would be mechanically simple to exploit once the specific authorization flaw is understood.
