Using an insecure protocol like HTTP or FTP to download your dependencies leaves your Maven build vulnerable to a Man in the Middle (MITM). This can allow attackers to inject malicious code into the artifacts that you are resolving and infect build artifacts that are being produced. This can be used by attackers to perform a Supply chain attack against your project’s users.

This vulnerability has a CVSS v3.1 base score of 8.1/10 .

Recommendation

Always use HTTPS or SFTP to download artifacts from artifact servers.

Example

These examples show examples of locations in Maven POM files where artifact repository upload/download is configured. The first shows the use of HTTP, the second shows the use of HTTPS.
