CVE-2026-34286Network attack vector

Unauthenticated read and modification of critical data

Published Apr 21, 2026 · Updated Apr 21, 2026

Missing authentication in Oracle Identity Manager Connector 12.2.1.4.0 allows remote attackers to read and modify critical data via HTTPS. Oracle identifies the affected locus only as the Core component and has not published the request path, handler, or authentication operation that fails. No credentials or user interaction are required; successful requests can read all connector-accessible data and create, delete, or modify critical records.
