A cross-site request forgery vulnerability exists in Jenkins Warnings Next Generation Plugin 2.1.1 and earlier in src/main/java/io/jenkins/plugins/analysis/warnings/groovy/GroovyParser.java that allows attackers to execute arbitrary code via a form validation HTTP endpoint.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
