Oracle BI EE Critical Flaw CVE-2026-91241 Allows High-Privilege Remote Takeover

The National Vulnerability Database recorded a critical security flaw in Oracle Business Intelligence Enterprise Edition on a recent update cycle. Identified as CVE-2026-91241, this vulnerability carries a CVSS 3.1 Base Score of 9.1, indicating severe risk. The defect resides within the Analytics Web Administration component of the Oracle Analytics product suite. This high-severity rating reflects the ease of exploitation and the significant impact on confidentiality, integrity, and availability.

According to the NVD record, the vulnerability allows a high-privileged attacker with network access via HTTP to compromise the system. The attack vector is network-based, requiring low complexity for execution. Although the initial access requires high privileges, the successful exploitation results in a complete takeover of the Oracle Business Intelligence Enterprise Edition. The CVSS vector string CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H confirms the critical nature of the exposure.

Scope and Impact Assessment

The vulnerability exhibits a scope change, meaning attacks may significantly impact additional products beyond the initial component. While the primary target is the Analytics Web Administration interface, the compromise extends to the broader Oracle Business Intelligence Enterprise Edition environment. This expansion of scope contributes to the high severity rating. Attackers can achieve high levels of confidentiality, integrity, and availability impacts. The potential for remote takeover makes this a significant concern for enterprises relying on these analytics tools for business intelligence operations.

Affected Versions and Products

Oracle Analytics products in specific versions are susceptible to this exploit. The NVD record explicitly lists Oracle Business Intelligence Enterprise Edition versions 8.2.0.0.0, 12.2.1.4.0, and 26.01.0.0.0 as supported versions that are affected. Organizations running any of these three version strings should assume their systems are vulnerable. The component involved is the Analytics Web Administration, which serves as the management interface for the analytics platform. Users of other versions or components are not listed in this specific advisory.

What should you do?

The source material does not state whether a patch or fix is available. Security teams should monitor official Oracle security alerts and the NVD for further updates. Until a vendor update is provided, administrators should restrict network access to the Analytics Web Administration interface. Limiting HTTP access to trusted internal networks reduces the attack surface. Reviewing high-privileged account usage can help detect unauthorized access attempts. Organizations should verify their current version against the affected list to determine exposure.

What to do and how to stay safe: Oracle

• Verify if your environment runs Oracle Analytics versions 8.2.0.0.0, 12.2.1.4.0, or 26.01.0.0.0 to determine exposure.
• Restrict HTTP network access to the Analytics Web Administration component to trusted internal IP addresses only.
• Monitor logs for unusual activity from high-privileged accounts accessing the web administration interface.
• Watch for official security advisories from Oracle regarding patches for CVE-2026-91241.
