Low-privilege unauthorized data read and write
Published Aug 18, 2026 · Updated Aug 19, 2026
Improper access control in Imperative Web Server in Oracle Helidon 3.2.18 allows remote authenticated users to read and modify data via HTTP. Oracle has not published the affected endpoint, handler, or authorization check, so the specific operation that accepts insufficiently authorized requests is undisclosed in the public record. Reachability requires low-privileged application access over the network, and the published impact is limited to unauthorized reads plus update, insert, or delete access to a subset of Helidon-accessible data.
