Affecting com.beust:jcommander artifact, versions [0,1.75)

Overview

com.beust:jcommander is a Command line parsing framework for Java.

Affected versions of this package are vulnerable to Unsafe Dependency Resolution due to resolving dependencies over an insecure channel (http).

If the build occurred over an insecure connection, a malicious user could have perform a Man-in-the-Middle attack during the build and alter the build artifacts that were produced. In the case that any of these artifacts were compromised, any developers using them could be vulnerable.

Note: In order to validate that this artifact was not compromised, the maintainer would need to confirm that all of the artifacts published to the registry were not altered. Until this happens, we can not guarantee that this artifact was not compromised even though the probability that this happened is low.

We have chosen to alert on this issue when maintainers either decided to issue CVEs themselves, or in cases when maintainers decided against performing audits on their build to verify they had not been compromised.

Remediation

Upgrade com.beust:jcommander to version 1.75 or higher.
