Description
A exposure of sensitive information vulnerability exists in Jenkins Openstack Cloud Plugin 2.35 and earlier in BootSource.java, InstancesToRun.java, JCloudsCleanupThread.java, JCloudsCloud.java, JCloudsComputer.java, JCloudsPreCreationThread.java, JCloudsRetentionStrategy.java, JCloudsSlave.java, JCloudsSlaveTemplate.java, LauncherFactory.java, OpenstackCredentials.java, OpenStackMachineStep.java, SlaveOptions.java, SlaveOptionsDescriptor.java that allows attackers with Overall/Read access to Jenkins to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins, and to cause Jenkins to submit HTTP requests to attacker-specified URLs.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.jenkins-ci.plugins:openstack-cloud, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.jenkins-ci.plugins:openstack-cloud to 2.37 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2018-1000603 is resolved across your whole dependency graph.
Workarounds
Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.
