Hi,

The following vulnerability was published for puma.

CVE-2022-23634[0]:
| Puma is a Ruby/Rack web server built for parallelism. Prior to `puma`
| version `5.6.2`, `puma` may not always call `close` on the response
| body. Rails, prior to version `7.0.2.2`, depended on the response body
| being closed in order for its `CurrentAttributes` implementation to
| work correctly. The combination of these two behaviors (Puma not
| closing the body + Rails' Executor implementation) causes information
| leakage. This problem is fixed in Puma versions 5.6.2 and 4.3.11. This
| problem is fixed in Rails versions 7.02.2, 6.1.4.6, 6.0.4.6, and
| 5.2.6.2. Upgrading to a patched Rails _or_ Puma version fixes the
| vulnerability.

Note that the respective rails CVE is CVE-2022-23633.

If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
