A flaw was found in Jenkins. Secrets submitted via POST config.xml are stored unencrypted in job configuration files on the Jenkins controller. This allows users with 'Item/Extended Read' permission, or those with direct access to the Jenkins controller file system, to view sensitive information. This vulnerability leads to information disclosure.
