CVE-2026-34288Network attack vector

Unauthenticated disclosure of all accessible connector data

Published Apr 21, 2026 · Updated Apr 21, 2026

Information disclosure in Oracle Identity Manager Connectors 12.2.1.4.0 allows remote attackers to read critical data through HTTP requests. Oracle identifies the affected locus only as the Core component and does not disclose the flawed operation or crafted input that triggers it. Exploitation requires no credentials or user interaction but has high attack complexity; successful attacks expose critical data or all data accessible to the connector.
