Summary

CMAK through 3.0.0.6 fails to apply the scheduled leader election feature toggle to HTML form routes, allowing attackers to bypass the feature gate. Attackers can access the form endpoints to start and stop the recurring election scheduler, disrupting leadership across managed Kafka clusters.

Risk Assessment

Disrupting leader election in Kafka clusters can cause service unavailability and data loss. An unauthorized user can affect critical streaming infrastructure.

Recommendation

Upgrade CMAK beyond version 3.0.0.6. Restrict access to the CMAK interface and protect form endpoints with authentication and authorization.

Other vulnerabilities in CMAK

CVE-2026-92751High
CMAK through 3.0.0.6 fails to install a cross-site request forgery filter, allowing attackers to perform state-changing actions on behalf of authenticated operators. Attackers can craft hidden forms that submit to destructive endpoints like topic deletion and cluster configuration changes, leveraging the operator's HTTP Basic authentication credentials or play-basic-authentication cookie without SameSite protection.
