Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Jenkins Nexus Platform Plugin 3.18.0-03 and earlier (Maven org.sonatype.nexus.ci:nexus-jenkins-plugin, versions below 3.18.1-01) lacks permission checks in form validation methods. An attacker with Overall/Read permission can make Jenkins connect to a server they specify using credential IDs they obtained elsewhere, which can expose stored Jenkins credentials. The same methods also accept GET requests, enabling cross-site request forgery. Upgrade to 3.18.1-01, which requires POST requests and Overall/Administer permission.
