Authenticated partial data disclosure and modification
Published Aug 18, 2026 · Updated Aug 20, 2026
Improper access control in Oracle Helidon 4.5.0 allows remote authenticated users to read and modify application-accessible data. Oracle identifies the Imperative Web Server component but has not published the affected code locus or incorrect authorization operation. Low-privileged HTTP access is required; exploitation exposes a subset of accessible data and permits some updates, insertions, or deletions.
