GoCD is a continuous delivery server. GoCD versions 19.11.0 through 21.4.0 (inclusive) are vulnerable to a Document Object Model (DOM)-based cross-site scripting attack via a pipeline run\'s Stage Details > Graphs tab. It is possible for a malicious script on a attacker-hosted site to execute script that will run within the user\'s browser context and GoCD session via abuse of a messaging channel used for communication between with the parent page and the stage details graph\'s iframe. This could allow an attacker to steal a GoCD user\'s session cookies and/or execute malicious code in the user\'s context. This issue is fixed in GoCD 22.1.0. There are currently no known workarounds.
