Root Cause Analysis

The vulnerability stems from unescaped injection of the redirect URL into HTML. In Jenkins plugin architecture:

Data providers like getRedirectUrl() in Action classes feed values to Jelly views
The pre-patch Jelly template likely contained a vulnerable ${action.redirectUrl} reference without escaping
While the actual XSS occurs during view rendering, the runtime call stack during exploitation would show the getRedirectUrl() method as the source of untrusted data
The patch's focus on 'escaping the shortcut redirection URL' indicates the value from this method was being used unsafely in output contexts
