Question 1

What happens when Cloud Sql Auth Proxy reaches end of life?

Accepted Answer

When Cloud Sql Auth Proxy reaches end of life, it stops receiving security patches, bug fixes, and new features.  The latest supported version is Cloud Sql Auth Proxy 2. Running an EOL version exposes your systems to unpatched security vulnerabilities with no official fix available.

Question 2

Is Cloud Sql Auth Proxy 2 still supported?

Accepted Answer

Yes. Cloud Sql Auth Proxy 2 is actively supported. It receives security patches and bug fixes. Check the version table above for the full list of supported Cloud Sql Auth Proxy releases and their exact end-of-life dates.

Question 3

Is it safe to use Cloud Sql Auth Proxy after end of life?

Accepted Answer

No. Running Cloud Sql Auth Proxy after EOL is not safe for production systems. Once a version reaches end of life, newly discovered CVEs are published publicly but never patched — leaving your systems permanently exposed. The only safe path is upgrading to an actively supported Cloud Sql Auth Proxy release.

Question 4

How to upgrade from Cloud Sql Auth Proxy 1 to Cloud Sql Auth Proxy 2.x?

Accepted Answer

To upgrade Cloud Sql Auth Proxy from 1 to 2: (1) review the official migration guide for breaking changes, (2) test your application against the new version in a staging environment, (3) update dependencies that have version constraints, (4) run your full test suite, (5) deploy with a rollback plan. The earlier you start, the more time you have to resolve compatibility issues before EOL.

Question 5

When is the next Cloud Sql Auth Proxy LTS version?

Accepted Answer

Not all Cloud Sql Auth Proxy releases have a designated LTS status. Check the version table above — LTS releases are marked with an "LTS" badge. Refer to the official Cloud Sql Auth Proxy release policy for information on upcoming long-term support versions.

Question 6

How long does Cloud Sql Auth Proxy support each version?
