Cross-site Scripting in Jenkins Autocomplete Parameter Plugin

Jenkins Autocomplete Parameter Plugin 1.1 and earlier references Dropdown Autocomplete parameter and Auto Complete String parameter names in an unsafe manner from Javascript embedded in view definitions, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Item/Configure permission.

While this looks similar to SECURITY-2729, this is an independent problem and exploitable even on views rendering parameters that otherwise attempt to prevent XSS vulnerabilities in parameter names.
