AnalysisAIv1 – Sep 15, 2026

Oracle BI Publisher 12.2.1.4.0, the enterprise reporting tier of Oracle Analytics, lets a low-privileged network attacker reach data well beyond their granted entitlements and partially degrade the service through crafted HTTP requests to the BI Publisher Security component. Oracle scores it 8.5 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:L), and the scope-change metric indicates that a compromised deployment can expose additional, integrated Oracle products that trust BI Publisher. No public exploit code, CISA KEV listing, or EPSS estimate was supplied with the source data, so exploitation status at time of analysis is 'no public exploit identified' and remediation depends on the referenced Oracle security alert.

Attack Technique

Authentication Bypass CRITICAL

Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.

Denial of Service MEDIUM

Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
