Jenkins Warnings Next Generation Plugin 9.10.2 and earlier does not restrict the name of a file when configuring custom ID, allowing attackers with Item/Configure permission to write and read specific files with a hard-coded suffix on the Jenkins controller file system.

Jenkins Warnings Next Generation Plugin 8.4.4 and earlier does not perform a permission check in methods implementing form validation, allowing attackers with Item/Read permission but without Item/Workspace or Item/Configure permission to check whether attacker-specified file patterns match workspace contents.

A cross-site request forgery vulnerability in Jenkins Warnings NG Plugin 5.0.0 and earlier allowed attackers to reset warning counts for future builds.

A cross-site scripting vulnerability in Jenkins Warnings NG Plugin 5.0.0 and earlier allowed attacker with Job/Configure permission to inject arbitrary JavaScript in build overview pages.

A cross-site scripting vulnerability exists in Jenkins Warnings Next Generation Plugin 1.0.1 and earlier in src/main/java/io/jenkins/plugins/analysis/core/model/DetailsTableModel.java, src/main/java/io/jenkins/plugins/analysis/core/model/SourceDetail.java, src/main/java/io/jenkins/plugins/analysis/core/model/SourcePrinter.java, src/main/java/io/jenkins/plugins/analysis/core/util/Sanitizer.java, src/main/java/io/jenkins/plugins/analysis/warnings/DuplicateCodeScanner.java that allows attackers with the ability to control warnings parser input to have Jenkins render arbitrary HTML.

A cross-site request forgery vulnerability exists in Jenkins Warnings Next Generation Plugin 2.1.1 and earlier in src/main/java/io/jenkins/plugins/analysis/warnings/groovy/GroovyParser.java that allows attackers to execute arbitrary code via a form validation HTTP endpoint.
