Authenticated data disclosure and modification
Published Sep 15, 2026 · Updated Sep 15, 2026
Improper access control in Oracle WebCenter Portal 12.2.1.4.0 and 14.1.2.0.0 allows remote authenticated users to read and alter portal data via HTTP. The flaw resides in the Security Framework, but Oracle has not disclosed the affected request handler or incorrect authorization operation. Low-privileged access is required; successful exploitation exposes critical portal data and permits some updates, insertions, or deletions.
