Upgrade org.jenkins-ci.plugins:script-security to version 1.5.3 or higher.

Overview

org.jenkins-ci.plugins:script-security package that allows Jenkins administrators to control what in-process scripts can be run by less-privileged users.

Affected versions of this package are vulnerable to Arbitrary Code Execution in RejectASTTransformsCustomizer.java. It is possible for attackers with Overall/Read permission to provide a Groovy script to an HTTP endpoint that can result in arbitrary code execution on the Jenkins master JVM.
