Unauthenticated access to all accessible data
Published Sep 15, 2026 · Updated Sep 15, 2026
Information disclosure in Oracle WebCenter Sites 12.2.1.4.0 and 14.1.2.0.0 allows remote attackers to read critical data via HTTP. Oracle has not publicly identified the affected request handler or the incorrect operation it performs on untrusted HTTP input. Network access without authentication is sufficient, and successful exploitation exposes critical or all otherwise accessible WebCenter Sites data.
