CVE-2026-33013
HighSummary
Framework Micronaut w wersjach wcześniejszych niż 4.10.16 i 3.10.5 nieprawidłowo obsługuje malejący porządek indeksów tablicy podczas wiązania ciała form-urlencoded, co może prowadzić do pętli nieskończonej, wyczerpania CPU oraz błędów OutOfMemoryError. Problem ten został naprawiony w wersjach 4.10.16 i 3.10.5.
Risk Assessment
Atakujący zdalnie mogą wykorzystać tę podatność do wywołania ataku DoS, co może prowadzić do zakłócenia działania aplikacji i obniżenia dostępności usług w organizacji.
Recommendation
Zaleca się aktualizację frameworka Micronaut do wersji 4.10.16 lub 3.10.5, aby zabezpieczyć się przed tą podatnością.

Original NVD description (English source)
Micronaut Framework is a JVM-based full stack Java framework designed for building modular, easily testable JVM applications. Versions prior to both 4.10.16 and 3.10.5 do not correctly handle descending array index order during form-urlencoded body binding in theJsonBeanPropertyBinder::expandArrayToThreshold, which allows remote attackers to cause a DoS (non-terminating loop, CPU exhaustion, and OutOfMemoryError) via crafted indexed form parameters (e.g., authors[1].name followed by authors[0].name). This issue has been fixed in versions 4.10.16 and 3.10.5.
