CVE-2026-21940Network attack vector

Unauthenticated data disclosure via undisclosed HTTP flaw

Published Jan 20, 2026 · Updated Jan 20, 2026

Information disclosure in Oracle Agile PLM 9.3.6 allows remote attackers to read critical or all application-accessible data via HTTP. Oracle identifies the User and User Group component but has not published the affected endpoint or request-handling error that exposes data. No authentication or user interaction is required; network access to the HTTP service is sufficient, and the reported effect is limited to confidentiality.
