Jenkins Plugin Installation Manager Tool is part of the Jenkins project Docker images. As jenkins-plugin-cli it is used to download and install plugins even before Jenkins is running.
Jenkins Plugin Installation Manager Tool 2.1.3 and earlier does not verify plugin downloads. This may allow third parties such as mirror operators to provide crafted plugin downloads.
Jenkins Plugin Installation Manager Tool 2.2.0 confirms that actual checksums of downloaded plugin match the expected checksums.
Docker images of Jenkins 2.269 and 2.263.1 contain Plugin Installation Manager Tool 2.2.0. Users of older Docker images can change the version they use by extending the Jenkins image and update the tool themselves with:
ARG PLUGIN_CLI_URL=https://github.com/jenkinsci/plugin-installation-manager-tool/releases/download/2.2.0/jenkins-plugin-manager-2.2.0.jar RUN curl -fsSL ${PLUGIN_CLI_URL} -o /usr/lib/jenkins-plugin-manager.jar Jenkinsfile Runner 1.0-beta-22 Docker images also include Plugin Installation Manager Tool 2.2.0.
