CVE-2021-29479, GHSA-w6rq-6h34-vh7q

HTTP Request Smuggling
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. F, 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 As a workaround, ensure that ServerConfigBuilder::publicAddress
correctly configures the server in production.
