CVE-2026-61021Network attack vector

Application takeover by low-privilege users

Published Aug 18, 2026 · Updated Aug 20, 2026

Unspecified vulnerability in Oracle WebCenter Sites 12.2.1.4.0 and 14.1.2.0.0 allows remote authenticated users to take over the application via HTTP. Oracle's public advisory identifies only the WebCenter Sites component and states that low-privileged HTTP requests can compromise the product; it does not disclose the vulnerable endpoint, code path, or input-handling error. Reachability requires valid low-privilege access rather than anonymous internet exposure, but successful exploitation has full confidentiality, integrity, and availability impact and may affect additional products because Oracle scored the issue with scope change.
