## What changed

**1. Added: Update** (identified) · 2026-10-21 00:42 UTC

```diff
+ We continue to mitigate CVE-2026-111943. We encourage all customers to apply updates from their operating system vendor that remove eMudhra from their trust store and to update to a patched version of Teleport that does not validate certificates that eMudhra issues. Teleport 18.11.6 and 17.7.31 do not validate certificates that eMudhra issues. For self-hosted customers, we encourage you to update all Teleport services to Teleport 18.11.6 and 17.7.31 as soon as possible. Downloads can be obtained from your dashboard directly or through all package managers maintained by Teleport, including apt, yum, and helm. Users should back up the Teleport cluster, then follow the standard Teleport upgrade procedure. For Cloud customers, no action is required at this time. We are rolling any Teleport and Teleport Cloud components that this issue might affect and pushing out agent and tools updates through Managed Updates. Cloud customers may experience intermittent connectivity issues if a Teleport Cloud component we are updating doesn’t support connection resumption. We expect this process to last at least through the end of the week. You can share this message with customers with the following link: https://status.teleport.sh/incidents/gzpxt06ftn8z We will post an update by 10/21/26 9:00 AM PDT or sooner if we have additional updates.
