In affected versions sending an invalid Content Type header leads to memory leak in DefaultArgumentConversionContext as this type is erroneously used in static state. ### Impact Sending an invalid Content Type header leads to memory leak in `DefaultArgumentConversionContext` as this type is erroneously used in static state. ### Patches The problem is patched in Micronaut 3.2.7 and above. ### Workarounds The default content type binder can be replaced in an existing Micronaut application to mitigate the issue: ```java package example; import java.util.List; import io.micronaut.context.annotation.Replaces; import io.micronaut.core.convert.ConversionService; import io.micronaut.http.MediaType; import io.micronaut.http.bind.DefaultRequestBinderRegistry; import io.micronaut.http.bind.binders.RequestArgumentBinder; import jakarta.inject.Singleton; @Singleton @Replaces(DefaultRequestBinderRegistry.class) class FixedRequestBinderRegistry extends DefaultRequestBinderRegistry { public FixedRequestBinderRegistry(ConversionService conversionService, List<RequestArgumentBinder> binders) { super(conversionService, binders); } @Override protected void registerDefaultConverters(ConversionService<?> conversionService) { super.registerDefaultConverters(conversionService); conversionService.addConverter(CharSequence.class, MediaType.class, charSequence -> { try { return MediaType.of(charSequence); } catch (IllegalArgumentException e) { return null; } }); } } ``` ### References Commit that introduced the vulnerability https://github.com/micronaut-projects/micronaut-core/commit/b8ec32c311689667c69ae7d9f9c3b3a8abc96fe3 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Micronaut Core](https://github.com/micronaut-projects/micronaut-core/issues) * Email us at [info@micronaut.io](mailto:info@micronaut.io)"}, {"lang": "es", "value": "Micronaut es un marco de trabajo Java de pila completa basado en JVM dise\u00f1ado para construir aplicaciones web JVM con soporte para Java, Kotlin y el lenguaje Groovy.
