GHSA-2hcp-gjrf-7fhc

DefaultHtmlErrorResponseBodyProvider in io.micronaut:micronaut-http-server since 4.7.0 and until 4.10.7 used an unbounded ConcurrentHashMap cache with no eviction policy. If the application throws an exception whose message may be influenced by an attacker, for example, including request query value parameters, this could be used by remote attackers to cause a denial of service (unbounded heap growth and OutOfMemoryError).

Fixed via: https://github.com/micronaut-projects/micronaut-core/commit/1e2ba2c14386af3d47751732d02053a72b0b49b3
