CVE-2019-10343: Jenkins Configuration as Code Plugin 1.24 and earlier did not properly apply masking to values expected to...

Security readout for executives and security teams

Jenkins Configuration as Code Plugin 1.24 and earlier could write values meant to be hidden into logs while applying configuration. This is a secret-exposure issue: passwords, tokens, or other sensitive configuration values may have been visible to anyone with access to those logs. Organizations using Jenkins with Configuration as Code Plugin 1.24 or earlier are potentially exposed, especially where configuration application logs are retained or broadly accessible. Risk depends on whether sensitive values were present in applied configuration and who can read Jenkins logs. Treat this as a targeted cleanup priority for Jenkins environments, not an emergency exploitation alert. The business risk is credential exposure through logs, so prioritize inventory, upgrade, log review, and credential rotation where exposure is confirmed. Mitigation focus: Identify Jenkins instances using Configuration as Code Plugin 1.24 or earlier.; Update the plugin according to Jenkins advisory guidance.; Review Jenkins logs from configuration-apply periods for exposed sensitive values..
