Jenkins AnchorChain Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Jenkins AnchorChain Plugin version 1.0. The vulnerability arises because the plugin does not restrict URL schemes for links created from workspace content, allowing the inclusion of 'javascript:' links. This issue is exploitable by attackers who can manipulate the input file for the Anchor Chain post-build step.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user.
