Description
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
NVD description
Micronaut Framework is a JVM-based full stack Java framework designed for building modular, easily testable JVM applications. Versions 4.7.0 through 4.10.16 used an unbounded ConcurrentHashMap cache with no eviction policy in its DefaultHtmlErrorResponseBodyProvider. If the application throws an exception whose message may be influenced by an attacker, (for example, including request query value parameters) it could be used by remote attackers to cause an unbounded heap growth and OutOfMemoryError, leading to DoS. This issue has been fixed in version 4.10.7.
