Oracle Business Intelligence Enterprise Edition: Privilege escalation in Platform Security
Summary
Oracle Business Intelligence Enterprise Edition versions 8.2.0.0.0 and 12.2.1.4.0 contain a vulnerability in the Platform Security component. An attacker with logon access to the infrastructure where the product runs can compromise the BI platform, with a CVSS 3.1 base score of 7.8.

Workaround
Unknown. The CVE record provides no workaround. Interim measure: restrict who can log on to the BI host and its infrastructure.
Exploitation
- Not listed in CISA KEV.
- CISA SSVC: exploitation none, not automatable, technical impact total.
- No public proof of concept or in-the-wild exploitation known at the time of research.
Our recommendation
- Confirm whether 8.2.0.0.0 or 12.2.1.4.0 (or 26.1.0.0.0) is in use.
- Apply the October 2026 Critical Patch Update for Oracle Analytics from the Patch Availability Document, not only this CVE.
- Until patched, limit logon access to the BI server and its management infrastructure.
- Monitor CISA KEV and Oracle advisories for exploitation signals.
Public exploits
