SCA: security update for io.ratpack:ratpack-core (GHSA-w6rq-6h34-vh7q)

medium Tenable Self-Hosted Container Security Plugin ID 419758

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Ratpack is a toolkit for creating web applications. In versions prior to 1.9.0, a user supplied
 `X-Forwarded-Host` header can be used to perform cache poisoning of a cache fronting a Ratpack server if
 the cache key does not include the `X-Forwarded-Host` header as a cache key. Users are only vulnerable if
 they do not configure a custom `PublicAddress` instance. For versions prior to 1.9.0, by default, Ratpack
 utilizes an inferring version of `PublicAddress` which is vulnerable. This can be used to perform redirect
 cache poisoning where an attacker can force a cached redirect to redirect to their site instead of the
 intended redirect location. The vulnerability was patched in Ratpack 1.9.0. As a workaround, ensure that
 `ServerConfigBuilder::publicAddress` correctly configures the server in production. (CVE-2021-29479)
