Jenkins Pipeline: Stage View Plugin allows CSRF protection bypass of any target URL in Jenkins

Jenkins Pipeline: Stage View Plugin provides a visualization of Pipeline builds. It also allows users to interact with input steps from Pipeline: Input Step Plugin.

Pipeline: Stage View Plugin 2.26 and earlier does not correctly encode the ID of input steps when using it to generate URLs to proceed or abort Pipeline builds.

This allows attackers able to configure Pipelines to specify input step IDs resulting in URLs that would bypass the CSRF protection of any target URL in Jenkins.
