CVE-2025-62714: Karmada Dashboard API Unauthorized Access Vulnerability

Should you act?

Normal patch cycle

No exploitation signal; fix it in your next routine update if you are affected. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
• EPSS 0.5%, percentile 41: FIRST’s model estimates a 0.5% chance of exploitation activity in the next 30 days, higher than 41% of all scored CVEs (low). EPSS is a probability, not a verdict.
• Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
• Only applies if your dependency tree includes github.com/karmada-io/dashboard (Go) < 0.2.0, fixed in 0.2.0. Check your lockfile, including transitive dependencies.

What it is

Karmada Dashboard is a general-purpose, web-based control panel for Karmada which is a multi-cluster management project. Prior to version 0.2.0, there is an authentication bypass vulnerability in the Karmada Dashboard API. The backend API endpoints (e.g., /api/v1/secret, /api/v1/service) did not enforce authentication, allowing unauthenticated users to access sensitive cluster information such as Secrets and Services directly. Although the web UI required a valid JWT for access, the API itself remained exposed to direct requests without any authentication checks. Any user or entity with network access to the Karmada Dashboard service could exploit this vulnerability to retrieve sensitive data.

From the GitHub advisory

Impact This is an authentication bypass vulnerability in the Karmada Dashboard API. The backend API endpoints (e.g., /api/v1/secret, /api/v1/service) did not enforce authentication, allowing unauthenticated users to access sensitive cluster information such as Secrets and Services directly. Although the web UI required a valid JWT for access, the API itself remained exposed to direct requests without any authentication checks. Any user or entity with network access to the Karmada Dashboard service could exploit this vulnerability to retrieve sensitive data.

Patches The issue has been fixed in Karmada Dashboard v0.2.0. This release enforces authentication for all API endpoints. Users are strongly advised to upgrade to version v0.2.0 or later as soon as possible.

Workarounds If upgrading is not immediately feasible, users can mitigate the risk by:

- Restricting network access to the Karmada Dashboard service using Kubernetes Network Policies, firewall rules, or ingress controls. - Placing the Dashboard behind a reverse proxy that enforces authentication (e.g., OAuth2 proxy) to add an additional layer of security.
