CVE-2026-60403Network attack vector

Authenticated service hang or repeatable crash

Published Jul 21, 2026 · Updated Jul 21, 2026

Denial of service in Oracle TimesTen In-Memory Database 26.1.1.1.0 allows remote authenticated users to hang or crash it via HTTPS. Oracle identifies the Kubernetes Operator as the vulnerable component but has not published the request-processing operation that triggers the failure. Low-privileged credentials and network access to the Operator are required; successful attacks interrupt availability without reported data exposure or modification.
