How to fix?

Upgrade org.apache.maven:apache-maven to version 3.8.1 or higher.


Affected versions of this package are vulnerable to Resources Downloaded over Insecure Protocol. Apache Maven will follow repositories that are defined in a dependency’s Project Object Model (pom) which may be surprising to some users, resulting in potential risk if a malicious actor takes over that repository or is able to insert themselves into a position to pretend to be that repository. Maven is changing the default behavior to no longer follow http (non-SSL) repository references by default. More details available in the referenced urls.

If you are currently using a repository manager to govern the repositories used by your builds, you are unaffected by the risks present in the legacy behavior, and are unaffected by this vulnerability and change to default behavior. For more information about repository management, visit this page.
