Unauthenticated access to critical application data
Published Apr 21, 2026 · Updated Apr 21, 2026
Information disclosure in Oracle HCM Common Architecture 12.2.3 through 12.2.15 allows remote attackers to read critical data via HTTP. Oracle identifies Knowledge Integration as the affected component but has not published the request path, parameter, or incorrect operation that exposes the data. No authentication or user interaction is required, and exploitation provides access to critical or all product-accessible data without reported modification or service interruption.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
