CVE-2026-21978Network attack vector

Authenticated critical-data disclosure via undisclosed mechanism

Published Jan 20, 2026 · Updated Jan 20, 2026

Information disclosure in Oracle FLEXCUBE Universal Banking 14.0.0.0.0 through 14.8.0.0.0 allows remote authenticated users to read critical data. Oracle identifies the Relationship Pricing component but has not published the flawed operation or the input that reaches it. Low-privileged HTTP access is required, and successful exploitation exposes critical or all application-accessible data without altering it.
