SCA: security update for io.micronaut:micronaut-context (GHSA-8hjv-92q9-g4xj)

high Tenable Self-Hosted Container Security Plugin ID 441363

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Micronaut Framework is a JVM-based full stack Java framework designed for building modular, easily
testable JVM applications. From 4.3.0 to before 4.10.22, TimeConverterRegistrar caches DateTimeFormatter
instances in an unbounded ConcurrentHashMap<String, DateTimeFormatter> whose key is derived from the
@Format annotation pattern concatenated with the locale from the HTTP Accept-Language header. Because
Locale.forLanguageTag() accepts arbitrary BCP 47 private-use extensions (en-x-a001, en-x-a002, …), an
unauthenticated attacker can generate an unlimited number of unique cache keys by sending requests with
novel locale tags, growing the cache until heap memory is exhausted and the JVM crashes. This
vulnerability is fixed in 4.10.22. (CVE-2026-44241)

Solution

Update the io.micronaut:micronaut-context library and its related packages to version 4.10.22 or later.
