CVE-2026-60408 Overview
CVE-2026-60408 affects the Kubernetes Operator component of Oracle TimesTen In-Memory Database version 26.1.1.1.0. The vulnerability allows a low-privileged attacker with network access over HTTPS to read a subset of data accessible to TimesTen In-Memory Database. Exploitation does not require user interaction and has low attack complexity, making the flaw practical to abuse from within a network path that reaches the operator. Oracle disclosed the issue in the July 2026 Critical Patch Update advisory. Impact is limited to confidentiality; integrity and availability are not affected.
Critical Impact
Authenticated network attackers can obtain unauthorized read access to a subset of TimesTen In-Memory Database data through the Kubernetes Operator.
Affected Products
- Oracle TimesTen In-Memory Database 26.1.1.1.0
- Component: Kubernetes Operator
- Deployments exposing the operator over HTTPS to low-privileged network clients

Technical Details for CVE-2026-60408
Vulnerability Analysis
The flaw resides in the Kubernetes Operator component that manages Oracle TimesTen In-Memory Database instances in containerized environments. A low-privileged attacker with authenticated network access to the operator over HTTPS can invoke functionality that returns database-accessible data the caller should not see. The vulnerability falls under the Information Disclosure category and is scoped to confidentiality only. Because operators typically hold elevated privileges within a cluster to manage database custom resources, insufficient authorization checks on read paths can expose subsets of managed database content to any authenticated cluster user or service account that can reach the operator endpoint.
Root Cause
Oracle's advisory does not publish source-level detail, but the CVSS profile (PR:L, C:L, I:N, A:N) indicates a broken access control or missing authorization check on a read operation exposed by the Kubernetes Operator. An authenticated principal with minimal privileges gains read visibility beyond its intended scope [CWE-285-class weakness].
Attack Vector
The attack vector is network-based (AV:N) over HTTPS and requires low privileges (PR:L) with no user interaction (UI:N). An attacker with a valid but low-privileged credential or service account token that can reach the TimesTen Kubernetes Operator API sends crafted requests to endpoints that return database-scoped data. The operator returns a subset of TimesTen data without enforcing the caller's authorization boundary. No verified public proof-of-concept exists. EPSS reports a probability of 0.215% at percentile 11.936.
No verified exploit code is available. See the Oracle Security Alert July 2026 for vendor guidance.
Detection Methods for CVE-2026-60408
Indicators of Compromise
- Unexpected HTTPS requests from low-privileged service accounts or users to the TimesTen Kubernetes Operator API endpoints.
- Kubernetes audit log entries showing get, list, or watch verbs against TimesTen custom resources from principals outside the database administration group.
- Operator pod logs indicating repeated read operations returning database payloads to non-administrative callers.
Detection Strategies
- Enable Kubernetes API server audit logging and alert on access to timesten.oracle.com custom resources by unexpected identities.
- Baseline normal operator API traffic patterns and flag deviations in request volume or source identity.
- Correlate service account token usage against RBAC role bindings to identify privilege drift.
Monitoring Recommendations
- Forward Kubernetes audit logs and TimesTen Operator logs to a centralized SIEM for retention and analysis.
- Monitor egress from operator pods for anomalous data volumes that could indicate bulk extraction.
- Review RBAC bindings on TimesTen namespaces on a recurring cadence to enforce least privilege.
How to Mitigate CVE-2026-60408
Immediate Actions Required
- Apply the July 2026 Oracle Critical Patch Update for TimesTen In-Memory Database 26.1.1.1.0 as documented in the Oracle Security Alert July 2026.
- Inventory clusters running the TimesTen Kubernetes Operator and confirm the deployed operator image version.
- Restrict network reachability of the operator API to trusted administrative subnets and service accounts only.
Patch Information
Oracle addressed CVE-2026-60408 in the July 2026 Critical Patch Update. Administrators should upgrade the TimesTen Kubernetes Operator to the fixed release identified in Oracle's advisory. Refer to the Oracle Security Alert July 2026 for the specific patched version and upgrade procedure.
Workarounds
- Enforce strict Kubernetes RBAC on TimesTen custom resources, granting get, list, and watch verbs only to database administrators.
- Apply NetworkPolicy resources to restrict ingress to the TimesTen Operator pod to authorized namespaces.
- Rotate and scope service account tokens that have access to the operator, removing unused bindings.
