CVE-2026-62286 amir20 CVE debrief

Who should care

Defenders managing containerized environments with restricted user access in Dozzle deployments should assess exposure and prioritize mitigation to prevent unauthorized access to sensitive container information. This includes verifying and updating access controls, monitoring for potential security issues, and ensuring that restricted users do not receive resource telemetry and lifecycle events for containers outside their authorized label scope.

Why it matters

CVE-2026-62286 allows authenticated restricted users in Dozzle deployments to receive unauthorized container events, potentially exposing sensitive information. Defenders should prioritize verifying and mitigating this issue, especially those managing containerized environments with restricted user access.

• Potential unauthorized access to container resource telemetry
• Potential unauthorized access to container lifecycle events
• Need to verify and update access controls for restricted users
• Need to monitor containerized environments for potential security issues

Technical summary

The streamEvents function in internal/web/events.go of Dozzle applies label filters to container lists but not to container-stat and container-event channels. This allows authenticated restricted users to receive telemetry and lifecycle events for containers outside their authorized label scope, potentially exposing sensitive information such as container names, images, full label maps, CPU and memory use, network and disk totals, and deployment or restart activity across monitored hosts. Defenders should prioritize verifying and mitigating this issue, especially those managing containerized environments with restricted user access.

Defensive priority

Defenders should prioritize verifying and mitigating this issue, especially those managing containerized environments with restricted user access.

Recommended defensive actions

• Verify and apply the patch in version 10.6.7
• Review and update access controls for restricted users in Dozzle deployments
• Monitor containerized environments for potential unauthorized access to resource telemetry and lifecycle events
• Confirm whether affected Dozzle deployments exist in managed environments and assign an owner for follow-up.
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
