Security: In response to GCP-2026-071, Google is updating Cloud SQL's managed components.

In response to GCP-2026-071, Google is updating Cloud SQL's managed components. No manual updates to the certificate store are required for Cloud SQL-managed instances. The fix is shipping in a new maintenance version that will be applied during scheduled maintenance. You can also apply the fix by performing self-service maintenance. An announcement will be published when the self-service maintenance fix is available.

What should I do?

• If you use the Cloud SQL Auth Proxy, then upgrade the Cloud SQL Auth Proxy to 2.26.3 or later and the Cloud SQL Proxy Operator to 1.8.4 or later. If you run the standalone proxy binary, then also update the host's certificate authority (CA) certificates. • If you use a Cloud SQL Language Connector, then update the language runtime and operating system CA certificates used with the Cloud SQL Language Connector (for example, Go 1.26.10 or 1.27.3 or later, certifi 2026.10.19 or later). • If you're using the gcloud CLI to install the Cloud SQL Auth Proxy, then update the gcloud CLI to 590.0.1.
