Summary
Memory leak in micronaut-core
Details

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:

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;
            }
        });
    }
}
