CVE-2019-10443: Jenkins iceScrum Plugin stores credentials in Cleartext

The vulnerability stems from the iceScrum Plugin storing credentials unencrypted in job config.xml files. Jenkins plugins typically handle credential persistence via methods like saveCredentials() and retrieval via getCredentials(). The advisory explicitly states credentials were stored in cleartext, implying these functions did not use Jenkins' encrypted credential storage mechanisms (e.g., Secret class or CredentialsBinding). The high confidence comes from the pattern of similar vulnerabilities in Jenkins plugins and the explicit reference to config.xml storage in the CVE description.
