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

## Security Security In response to [GCP-2026-071](https://cloud.google.com/support/bulletins#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](https://cloud.google.com/sql/docs/sqlserver/maintenance). You can also apply the fix by [performing self-service maintenance](https://cloud.google.com/sql/docs/sqlserver/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](https://cloud.google.com/sql/docs/sqlserver/sql-proxy#install) and the Cloud SQL Proxy Operator to[1.8.4 or later](https://cloud.google.com/sql/docs/sqlserver/connect-proxy-operator). 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](https://cloud.google.com/sql/docs/sqlserver/connect-connectors) (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](https://cloud.google.com/sdk/gcloud#download%5Fand%5Finstall%5Fthe).
