CVE-2026-33012
HighSummary
Framework Micronaut w wersjach od 4.7.0 do 4.10.16 używał nieograniczonej pamięci podręcznej ConcurrentHashMap bez polityki usuwania w DefaultHtmlErrorResponseBodyProvider. W przypadku wystąpienia wyjątku, którego komunikat może być kontrolowany przez atakującego, może to prowadzić do nieograniczonego wzrostu pamięci i błędu OutOfMemoryError, co skutkuje atakiem DoS.
Risk Assessment
Organizacja może doświadczyć przestojów w działaniu aplikacji z powodu błędów pamięci, co może prowadzić do utraty dostępności usług. Atakujący mogą wykorzystać tę podatność do przeprowadzenia ataków DoS.
Recommendation
Zaleca się aktualizację frameworka Micronaut do wersji 4.10.7 lub nowszej, aby usunąć tę podatność. Należy również monitorować aplikacje pod kątem niekontrolowanego wzrostu pamięci.

Original NVD description (English source)
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.
