Scheduled

We currently have no indication that LaunchDarkly-hosted services or customer data are impacted by the publicly-disclosed compromised intermediate CA certificates from eMudhra (https://emudhra.we-have-a-problem.com/). This guidance applies to all LaunchDarkly instances: Commercial, EU, and Federal.

LaunchDarkly has already taken precautionary steps to secure our platform and has released updated versions of the Relay Proxy and SDKs used by our customers. We continue to monitor the situation and patch all non-critical services.

We highly recommend that customers immediately take the following steps to secure the network connection between their systems and LaunchDarkly:
- Update LaunchDarkly SDKs and Relay Proxy listed below to the latest version provided
- Ensure your application hosts disallow the compromised CAs
- Follow publicly-documented remediation steps for your application infrastructure to disallow compromised CAs: https://emudhra.we-have-a-problem.com/
