CVE-2026-60401: Oracle TimesTen Information Disclosure

CVE-2026-60401 Overview

CVE-2026-60401 is a medium-severity vulnerability in the Oracle TimesTen In-Memory Database, specifically within the Kubernetes Operator component. The affected version is 26.1.1.1.0. A low-privileged attacker with local logon access to the infrastructure running TimesTen can exploit this flaw to compromise the database. The vulnerability carries a scope change, meaning successful exploitation impacts resources beyond the vulnerable component. The confidentiality impact is high, potentially resulting in unauthorized access to all TimesTen-accessible data.

Critical Impact
An authenticated local attacker can obtain unauthorized read access to critical data across the TimesTen In-Memory Database, with a scope change that extends impact to additional products in the Kubernetes environment.

Affected Products

Oracle TimesTen In-Memory Database 26.1.1.1.0
Component: Kubernetes Operator
Deployments running the affected Operator in Kubernetes environments

Technical Details for CVE-2026-60401

Vulnerability Analysis

The vulnerability resides in the Kubernetes Operator component of Oracle TimesTen In-Memory Database. The Operator manages the lifecycle of TimesTen database instances deployed as containers within Kubernetes clusters. An attacker with existing low-privilege access to the infrastructure where TimesTen executes can leverage this weakness to read data they should not be authorized to view.

The attack complexity is low and does not require user interaction. The scope change indicates that the vulnerable Operator can influence resources managed under a different security authority. This is characteristic of Kubernetes Operators, which often hold service account privileges spanning multiple namespaces or workloads. Successful exploitation can yield complete read access to all TimesTen-accessible data.

Root Cause

Oracle has not published detailed root-cause analysis. Based on the CVSS profile and the affected component, the flaw likely stems from improper access control or insufficient isolation in the Kubernetes Operator's handling of database resources, credentials, or configuration state. The scope change suggests the Operator's service account or cached credentials can be abused to reach data outside the attacker's original authorization boundary.

Attack Vector

Exploitation requires local logon to the infrastructure that runs TimesTen, along with low-privileged credentials. An attacker who already has a foothold on a node hosting the TimesTen Operator, or who possesses limited Kubernetes API access, can interact with Operator-managed resources to extract sensitive database contents. No user interaction is required, and the attack complexity is low, making post-compromise abuse straightforward once initial access is obtained.

No public proof-of-concept exploit is available at the time of publication. See the Oracle Security Alert July 2026 for vendor-supplied technical detail.

Detection Methods for CVE-2026-60401

Indicators of Compromise

Unexpected kubectl or Kubernetes API calls originating from pods or service accounts associated with the TimesTen Operator namespace.
Anomalous read access to TimesTen Custom Resource Definitions (CRDs), secrets, or configmaps holding database credentials.
Local shell activity on nodes hosting TimesTen pods by accounts that normally do not interact with the database tier.

Detection Strategies

Audit Kubernetes API server logs for get, list, and watch verbs against TimesTen CRDs, secrets, and pod exec endpoints by non-administrative identities.
Baseline the Operator service account's normal API call patterns and alert on deviations such as cross-namespace access or unusual resource reads.
Correlate host-level logon events on TimesTen nodes with subsequent Kubernetes API activity to identify lateral movement.

Monitoring Recommendations

Enable and centralize Kubernetes audit logs at the RequestResponse level for the namespaces hosting TimesTen and its Operator.
Monitor TimesTen database audit trails for query patterns inconsistent with application workloads.
Track EPSS trends for CVE-2026-60401; the current EPSS score is 0.145% (percentile 4.198), indicating low observed exploitation likelihood, but this can change post-disclosure.

How to Mitigate CVE-2026-60401

Immediate Actions Required

Inventory all Oracle TimesTen In-Memory Database deployments and confirm whether version 26.1.1.1.0 with the Kubernetes Operator is in use.
Apply the fixes bundled in the Oracle Critical Patch Update referenced in the Oracle Security Alert July 2026.
Restrict local logon and Kubernetes RBAC access to the infrastructure hosting TimesTen to the minimum set of administrators required.
Rotate TimesTen database credentials and Kubernetes service account tokens associated with the Operator after patching.

Patch Information

Oracle addresses CVE-2026-60401 in the July 2026 Critical Patch Update. Administrators should consult the Oracle Security Alert July 2026 for the exact patch identifiers, supported upgrade paths, and post-installation validation steps for the TimesTen Kubernetes Operator.

Workarounds

Enforce least-privilege Kubernetes RBAC policies for the Operator service account, scoping it to only the namespaces and resources it requires.
Apply Kubernetes Pod Security Standards or admission controllers to prevent unauthorized workload execution on nodes running TimesTen.
Segment the TimesTen infrastructure network so that low-privileged local accounts cannot reach the Kubernetes API server or Operator endpoints directly.
Enable Kubernetes secrets encryption at rest and rotate credentials frequently to limit the value of any data an attacker might obtain.

bash

# Example: restrict access to TimesTen namespace with a minimal RBAC role
# Review and apply after patching per Oracle guidance
kubectl create role timesten-operator-min \
  --verb=get,list,watch \
  --resource=timesten.oracle.com \
  --namespace=timesten

kubectl create rolebinding timesten-operator-min-binding \
  --role=timesten-operator-min \
  --serviceaccount=timesten:timesten-operator \
  --namespace=timesten
