A cross-site request forgery vulnerability exists in Jenkins Config File Provider Plugin 3.1 and earlier in ConfigFilesManagement.java, FolderConfigFileAction.java that allows creating and editing configuration file definitions.
A flaw was found in the config-file-provider Jenkins plugin. The plugin XML parser wasn't configure to prevent XML external entity (XXE) attacks. An attacker with the ability to define Maven configuration files can use this vulnerability to prepare a crafted configuration file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.
