Oracle Hyperion CVE-2026-62526

Exploitation requires three simultaneous conditions: (1) the attacker must hold high-privilege credentials on Oracle Hyperion Infrastructure Technology version 11.2.25.0.000 specifically - exploitation by lower-privileged or unauthenticated users is not supported by the CVSS vector (PR:H); (2) the attacker must have network access to the Hyperion Common Security HTTP interface; and (3) the attack complexity is rated High (AC:H), meaning the attacker must overcome additional conditions beyond simple access - such as specific timing windows, race conditions, or particular application state - that cannot be reliably replicated on demand. Exploitation is limited to integrity and availability impacts only; no confidentiality data is accessible through this vulnerability. Scope is unchanged (S:U), meaning successful exploitation cannot pivot to compromise systems beyond the Hyperion platform itself.

The CVSS 3.1 vector (AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:L/A:L) produces a base score of 3.3 and accurately characterizes this as a low-severity finding with severe exploitation prerequisites. An attacker must already hold high-level privileges on the Oracle Hyperion platform and must overcome high attack complexity before achieving only limited integrity and availability impact with no confidentiality breach. No EPSS data was included in the intelligence package, and this CVE is absent from the CISA Known Exploited Vulnerabilities catalog, confirming no evidence of active exploitation. No proof-of-concept exploit code has been identified. The practical threat model is narrow: this is most realistically exploitable by a malicious or compromised insider who already possesses administrative credentials - not an opportunistic external attacker. An SSVC disposition of 'Track' or 'Defer' is appropriate given zero public exploit evidence, no scope change, and minimal technical impact. The absence of a CWE classification is a data gap that slightly reduces confidence in root-cause understanding, though it does not elevate the risk posture given the other limiting signals.

An attacker who has already obtained high-privilege credentials to the Oracle Hyperion environment - through credential theft, insider access, or lateral movement from a compromised admin workstation - sends specially crafted HTTP requests to the Common Security component. By overcoming the high attack complexity requirement (which may involve timing, specific request sequencing, or state manipulation), the attacker achieves unauthorized modification of security-related data records or degrades service availability for other Hyperion users. No public exploit code exists to automate this scenario.
