Jenkins project · Jenkins Repository Connector Plugin
The Jenkins Repository Connector Plugin, version 2.0.2 and earlier, does not escape parameter names and descriptions shown for past builds, leaving a stored cross-site scripting flaw in the plugin's build-history display. An attacker who holds the Item/Configure permission can plant malicious script in those parameter fields, and it executes in the browser of users who later view the affected build pages.
