CVE-2021-26291: block repositories using http by default

First published: Fri Apr 23 2021(Updated: )

A flaw was found in maven. Repositories that are defined in a dependency’s Project Object Model (pom), which may be unknown to users, are used by default 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. The highest threat from this vulnerability is to data confidentiality and integrity.
