Authenticated data disclosure and modification via undisclosed flaw
Published Sep 15, 2026 · Updated Sep 15, 2026
Data exposure in Oracle BI Publisher 8.2.0.0.0, 12.2.1.4.0, and 26.01.0.0.0 allows remote authenticated users to read critical data via HTTP. Oracle identifies the Administration component but has not published the flawed request handler or the operation it performs incorrectly. Exploitation requires low-privileged access and interaction by another person, and also permits unauthorized updates, inserts, or deletions of some accessible data.
