CVE-2026-5483 Overview
A vulnerability has been identified in the odh-dashboard component of Red Hat OpenShift AI (RHOAI) that allows for the disclosure of Kubernetes Service Account tokens through a NodeJS endpoint. This flaw enables attackers with low-privilege access to potentially gain unauthorized access to Kubernetes resources by extracting sensitive authentication tokens through an exposed endpoint.
Critical Impact
Successful exploitation of this vulnerability could allow attackers to obtain Kubernetes Service Account tokens, enabling unauthorized access to cluster resources and potentially compromising the entire Kubernetes environment.
Affected Products
- Red Hat OpenShift AI (RHOAI) - odh-dashboard component
- OpenShift AI deployments utilizing the vulnerable NodeJS endpoint

Technical Details for CVE-2026-5483
Vulnerability Analysis
This vulnerability is classified as CWE-201 (Insertion of Sensitive Information Into Sent Data), indicating that the odh-dashboard component improperly includes sensitive Kubernetes Service Account tokens in data sent through a NodeJS endpoint. The flaw requires network access and low-privilege authentication, but the attack complexity is high due to specific conditions that must be met for successful exploitation. The scope is changed, meaning successful exploitation can affect resources beyond the vulnerable component's security scope, potentially impacting the broader Kubernetes cluster.
Root Cause
The root cause lies in improper handling of sensitive authentication data within the odh-dashboard NodeJS application. The vulnerable endpoint fails to properly sanitize or restrict access to Kubernetes Service Account tokens, allowing authenticated users to retrieve tokens they should not have access to. This represents a violation of the principle of least privilege and improper information exposure controls.
Attack Vector
The attack is network-based and requires an authenticated user with low privileges. An attacker would need to:
- Gain authenticated access to the OpenShift AI environment
- Identify and target the vulnerable NodeJS endpoint within odh-dashboard
- Craft requests to extract Kubernetes Service Account tokens
- Use the obtained tokens to access Kubernetes resources with the privileges of the compromised service account
The vulnerability's changed scope means that compromised tokens could provide access to resources across the Kubernetes cluster, extending beyond the odh-dashboard component itself.
Detection Methods for CVE-2026-5483
Indicators of Compromise
- Unusual API requests to odh-dashboard endpoints from authenticated but non-administrative users
- Unexpected access patterns to Kubernetes API endpoints using service account tokens
- Anomalous authentication events involving service account credentials outside normal operational contexts
Detection Strategies
- Monitor odh-dashboard access logs for requests to endpoints that may expose token information
- Implement Kubernetes audit logging to track service account token usage and detect unauthorized access attempts
- Deploy network monitoring to identify unusual communication patterns between odh-dashboard and Kubernetes API servers
- Review authentication logs for service account token usage that doesn't align with expected application behavior
Monitoring Recommendations
- Enable detailed logging for the odh-dashboard component to capture all endpoint requests
- Configure Kubernetes audit policies to log all authentication and authorization events
- Set up alerts for service account token usage from unexpected sources or IP addresses
- Implement continuous monitoring of Kubernetes RBAC permissions and access patterns
How to Mitigate CVE-2026-5483
Immediate Actions Required
- Review the Red Hat Security Advisory RHSA-2026:7397 and apply the appropriate patch for your deployment
- Audit existing service account tokens and rotate any that may have been compromised
- Review Kubernetes RBAC configurations to ensure service accounts have minimal required permissions
- Restrict network access to odh-dashboard endpoints to authorized users and systems only
Patch Information
Red Hat has released multiple security advisories addressing this vulnerability. Organizations should apply the appropriate patch based on their deployment version:
For additional details, consult the Red Hat CVE-2026-5483 Details page and Red Hat Bug Report #2454764.
Workarounds
- Implement network policies to restrict access to odh-dashboard endpoints from untrusted networks
- Apply additional authentication requirements for accessing sensitive dashboard functionality
- Consider temporarily disabling or restricting the vulnerable NodeJS endpoint until patches can be applied
- Implement service mesh policies to add an additional layer of authentication and authorization
