CVE-2026-60402: Oracle TimesTen In-Memory Database RCE Flaw

CVE-2026-60402 Overview

CVE-2026-60402 affects the Kubernetes Operator component of Oracle TimesTen In-Memory Database version 26.1.1.1.0. A low-privileged attacker with network access over HTTPS can compromise the database with low attack complexity. The flaw carries a CVSS 3.1 base score of 9.9 and includes a scope change, meaning successful exploitation can impact resources beyond the vulnerable component. Successful attacks result in full takeover of TimesTen In-Memory Database, with high impact on confidentiality, integrity, and availability. Oracle disclosed the issue in the July 2026 Critical Patch Update. EPSS data on 2026-07-23 reports a score of 0.328% at the 25.178 percentile.

Critical Impact
Authenticated network attackers can take over Oracle TimesTen In-Memory Database and pivot to affect additional products through the Kubernetes Operator scope change.

Technical Details for CVE-2026-60402

Vulnerability Analysis

The vulnerability resides in the Kubernetes Operator that manages Oracle TimesTen In-Memory Database deployments in containerized environments. Operators typically run with elevated cluster privileges to reconcile custom resources, manage pods, and mount secrets. An authenticated attacker reaching the Operator over HTTPS can abuse this trust boundary to compromise the database it manages. Oracle characterizes the flaw as easily exploitable and network reachable, requiring only low privileges and no user interaction. The scope change indicates that exploitation crosses the security authority of the vulnerable component, allowing effects on other Kubernetes-hosted workloads and Oracle products.

Root Cause

Oracle has not published a detailed technical root-cause analysis. The advisory lists the Kubernetes Operator as the affected component and confirms that a low-privileged, network-adjacent identity can achieve full takeover. The scope change and combined confidentiality, integrity, and availability impact are consistent with insufficient authorization enforcement or improper input handling in an Operator control-plane API served over HTTPS.

Attack Vector

Exploitation occurs over the network via HTTPS against the Kubernetes Operator endpoint. The attacker requires an existing low-privileged account or token that can reach the Operator. Successful exploitation leads to takeover of the TimesTen database instance and, due to the scope change, may compromise other workloads managed inside the cluster. See the Oracle Security Alert July 2026 for vendor guidance.

No verified proof-of-concept code has been published for CVE-2026-60402. The vulnerability mechanism is described in prose only pending further vendor disclosure.

Detection Methods for CVE-2026-60402

Indicators of Compromise

Unexpected HTTPS requests to the TimesTen Kubernetes Operator API from low-privileged service accounts or unknown pods.
New or modified TimesTenClassic or related custom resources not initiated by change management.
Operator-created pods, secrets, or role bindings that grant elevated access to the TimesTen namespace.
Outbound connections from TimesTen pods to unrecognized destinations following Operator API activity.

Detection Strategies

Enable Kubernetes API server audit logging and alert on Operator-scoped verbs (create, update, patch, delete) performed by non-administrative identities.
Monitor the Operator container logs for authentication events using tokens or certificates that do not match approved automation identities.
Correlate database privilege changes inside TimesTen with preceding Operator reconciliation events.

Monitoring Recommendations

Alert on service account token use outside of expected namespaces or nodes.
Track image, replica, and environment variable changes on TimesTen pods managed by the Operator.
Baseline HTTPS traffic to the Operator endpoint and flag deviations in source identity, volume, or request paths.

How to Mitigate CVE-2026-60402

Immediate Actions Required

Apply the fixes distributed in the Oracle Critical Patch Update - July 2026 to Oracle TimesTen In-Memory Database 26.1.1.1.0 deployments.
Restrict network reachability to the TimesTen Kubernetes Operator using NetworkPolicies and ingress controls.
Rotate service account tokens, kubeconfig credentials, and certificates that could reach the Operator API.
Review RBAC bindings and remove low-privileged identities that do not require access to the Operator or TimesTen namespaces.

Patch Information

Oracle addressed CVE-2026-60402 in the July 2026 Critical Patch Update. Administrators must apply the vendor-supplied patch for Oracle TimesTen In-Memory Database version 26.1.1.1.0. Refer to the Oracle Security Alert July 2026 for the exact patch identifiers, download locations, and installation prerequisites for both the database and the Kubernetes Operator container images.

Workarounds

Isolate the Operator namespace with strict NetworkPolicies limiting inbound HTTPS to trusted administrative sources.
Enforce least-privilege RBAC on the Operator ServiceAccount and remove cluster-wide permissions where scoping allows.
Enable Kubernetes API audit logging and forward events to a centralized monitoring pipeline for review.
Require mutual TLS or workload identity verification for any client interacting with the Operator API.
