Jenkins AnchorChain Plugin 1.0 does not limit URL schemes for links it creates based on workspace content, allowing the javascript: scheme.
This results in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to control the input file for the Anchor Chain post-build step.
As of publication of this advisory, there is no fix.
