vulnerability as referenced in the USN-5245-1 advisory.

  - 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 in 3.8.1+ 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. See this link for more
    information about repository management: https://maven.apache.org/repository-management.html
    (CVE-2021-26291)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
