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, a Maven package named org.sonatype.nexus.ci:nexus-jenkins-plugin, lacks permission checks in form validation methods and its XML parser is not hardened against external entities. An attacker with Overall/Read permission can make Jenkins send requests to an attacker-specified URL and parse the response, which can expose secrets from the Jenkins controller or enable server-side request forgery. Upgrade to 3.18.1-01, which fixes the XML parser and requires POST requests and Overall/Administer permission for the affected endpoints.
