CVE-2026-46843Network attack vector

Unauthenticated partial denial of service

Published May 28, 2026 · Updated May 28, 2026

Denial of service in Oracle REST Data Services 24.2.0 through 26.1.0 allows remote attackers to interrupt service via HTTPS. Oracle identifies the Core component but has not published the request, endpoint, or resource-consumption operation that triggers the condition. No authentication or user interaction is required, and the reported consequence is limited to a partial service interruption without confidentiality or integrity impact.
