Jenkins z/OS Connector Plugin allows local attacker to retrieve configured password

A exposure of sensitive information vulnerability exists in Jenkins z/OS Connector Plugin 1.2.6.1 and earlier in SCLMSCM.java that allows an attacker with local file system access or control of a Jenkins administrator's web browser (e.g. malicious extension) to retrieve the configured password. IBM z/OS Connector Plugin 2.0.0 and newer integrates with Credentials Plugin, no longer storing credentials itself.
