Affected: CleanStart: akhq

Package akhq version 0.27.1-r5 fixes 27 vulnerabilities: CVE-2026-58062, CVE-2026-59638, CVE-2026-59646, CVE-2026-12802, CVE-2026-59639...

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.

Affected: Maven: io.micronaut:micronaut-json-core

In `JsonBeanPropertyBinder::expandArrayToThreshold` in `io.micronaut:micronaut-json-core` before Micronaut 4 4.10.16 and in Micronaut 3 before 3.10.5 does not correctly handle descending array index order during form-urlencoded body binding, which allows remote attackers to cause a denial of service (non-terminating loop, CPU exhaustion, and OutOfMemoryError) via crafted indexed form parameters (e.g., `authors[1].name` followed by `authors[0].name`).

### Example

With such an application

```java package dosform;

import io.micronaut.http.HttpResponse; import io.micronaut.http.MediaType; import io.micronaut.http.annotation.Body; import io.micronaut.http.annotation.Consumes; import io.micronaut.http.annotation.Controller; import io.micronaut.http.annotation.Get; import io.micronaut.http.annotation.Post; import io.micronaut.http.annotation.Produces;

import java.net.URI;

@Controller class HomeController {

@Produces(MediaType.TEXT_HTML) @Get String index() { return """ <!DOCTYPE html> <html> <head> <title></title> </head> <body> <form action="/submit" method="post"> <label for="firstAuthor">Fist Author</label> <input id="firstAuthor" name="authors[0].name" type="text"/>

<label for="secondAuthor">Second Author</label> <input id="secondAuthor" name="authors[1].name" type="text"/> <label for="thirdAuthor">Third Author</lab…
