https://plugins.jenkins.io/aws-device-farm/ shows that there is a known security vulnerability in the AWS device farm plugin. That means the plugin maintainer was informed of the security vulnerability and given a reasonable amount of time to resolve it. It was not resolved, so the vulnerability was reported 3 years ago without a solution.
The last release of the plugin was two years ago. That release did not resolve the vulnerability. I think you can safely assume that the plugin is not being actively maintained.
If the plugin is a help to your company, you could propose that your company allow you to "adopt the plugin". There is a document that provides a series of incremental steps that a new contributor can take as they adopt a plugin. There is a five part video series that illustrates those steps.
Can we have an update on this please ?
