CVE-2026-60405 Overview
CVE-2026-60405 is an information disclosure vulnerability in the Oracle TimesTen In-Memory Database, specifically within the Kubernetes Operator component. The affected supported version is 26.1.1.1.0. A low-privileged attacker with local logon access to the infrastructure where TimesTen executes can exploit this flaw to gain unauthorized read access to a subset of TimesTen data. The scope changes during exploitation, so attacks against TimesTen may impact additional products beyond the vulnerable component itself. Oracle disclosed the vulnerability in the Oracle Security Alert for July 2026.
Critical Impact
A local, low-privileged attacker can obtain unauthorized read access to a subset of Oracle TimesTen In-Memory Database data through the Kubernetes Operator, with scope change affecting adjacent products.
Affected Products
- Oracle TimesTen In-Memory Database version 26.1.1.1.0
- Component: Kubernetes Operator
- Deployments where TimesTen executes on shared infrastructure accessible to local users

Technical Details for CVE-2026-60405
Vulnerability Analysis
The vulnerability resides in the Kubernetes Operator component that manages Oracle TimesTen In-Memory Database deployments. An attacker who can authenticate to the infrastructure hosting TimesTen can leverage the operator to read data they should not have access to. The attack is classified as local, meaning the adversary must already possess valid low-privileged credentials on the underlying system or cluster.
The issue produces a scope change, meaning the vulnerable component grants access to resources managed by a different security authority. In practice, this reflects the Kubernetes Operator's cross-boundary role between the TimesTen database and the Kubernetes control plane. Impact is limited to confidentiality; integrity and availability are unaffected.
Exploitation complexity is low and no user interaction is required. The EPSS probability of 0.137% reflects limited external exploitation interest as of publication, consistent with the local attack vector and low privilege gain.
Root Cause
Oracle has not published detailed root cause information beyond the Kubernetes Operator component designation. Based on the CVSS profile, the flaw stems from insufficient access control on operator-mediated resources, allowing a low-privileged local principal to observe database-managed data it should not see.
Attack Vector
The attacker needs local logon to the infrastructure where TimesTen executes, such as a shell in a co-tenant pod, a node account, or a Kubernetes service account with minimal permissions. From that foothold, the attacker interacts with the TimesTen Kubernetes Operator to retrieve a subset of accessible data. No social engineering or victim interaction is required.
No verified public proof-of-concept code is available. See the Oracle Security Alert for July 2026 for vendor guidance and patch references.
Detection Methods for CVE-2026-60405
Indicators of Compromise
- Unexpected read operations against TimesTen resources originating from low-privileged service accounts or co-tenant pods
- Kubernetes audit log entries showing unusual get, list, or watch verbs against TimesTen custom resources by non-administrative principals
- API access to the TimesTen Operator from namespaces that do not host TimesTen workloads
Detection Strategies
- Enable Kubernetes API server audit logging and alert on access to TimesTen custom resource definitions by unexpected identities
- Baseline normal operator interactions and flag deviations in principal, source pod, or verb frequency
- Correlate node-level shell activity with subsequent Kubernetes API calls targeting TimesTen resources
Monitoring Recommendations
- Forward Kubernetes audit logs, node authentication events, and TimesTen operator logs to a centralized analytics platform for correlation
- Monitor RBAC changes that grant read access to TimesTen-related resources, secrets, or config maps
- Track process execution and file access on TimesTen-hosting nodes for anomalous local logons
How to Mitigate CVE-2026-60405
Immediate Actions Required
- Apply the patches referenced in the Oracle Security Alert for July 2026 to Oracle TimesTen In-Memory Database 26.1.1.1.0 deployments
- Inventory clusters running the TimesTen Kubernetes Operator and prioritize those in multi-tenant environments
- Review and tighten RBAC bindings that grant access to TimesTen namespaces, custom resources, and operator service accounts
Patch Information
Oracle released fixes as part of the July 2026 Critical Patch Update cycle. Administrators should consult the Oracle Security Alert for July 2026 for the specific operator image version and upgrade instructions applicable to their deployment.
Workarounds
- Restrict local logon and pod scheduling on nodes that host TimesTen to trusted workloads only
- Enforce namespace isolation and NetworkPolicies so that only authorized pods can reach the TimesTen Operator API surface
- Remove unnecessary Kubernetes RBAC permissions on TimesTen custom resources for non-administrative accounts until patching is complete
# Review RBAC bindings referencing TimesTen resources
kubectl get clusterrolebindings -o json | \
jq '.items[] | select(.roleRef.name | test("timesten|ttoperator"; "i"))'
# List service accounts with access to the TimesTen namespace
kubectl get rolebindings -n <timesten-namespace> -o wide
