Adds one Java rule for the Jenkins plugin ruleset (
java/jenkins/info-exposure/):codevigilant.java.jenkins.info-exposure.controller-getenv-to-launcher(ERROR, CWE-200)Detects the generic vulnerable shape
new HashMap<>(System.getenv())(and the explicitHashMap<String, String>form). Pluginperform()/ descriptor code runs on the Jenkins controller JVM, so cloning the process environment and later passing that map toLauncher/ProcStarter.envs(or a remoting callable) copies controller secrets onto the agent-side child. The fix is to build a fresh env map containing only the variables the tool needs.Validated with
semgrep --validate --config java/. Positive repro (HashMap clone of System.getenv) fires 2/2; sanitized negative (empty HashMap populated with explicit keys, then.envs) stays silent.
