XSS in Gocd

CVE-2023-28629

GoCD is an open source continuous delivery server. GoCD versions before 23.1.0 are vulnerable to a stored XSS vulnerability, where pipeline configuration with a malicious pipeline label configuration can affect browser display of pipeline runs generated from that configuration. An attacker that has permissions to configure GoCD pipelines could include JavaScript elements within the label template, causing a XSS vulnerability to be triggered for any users viewing the Value Stream Map or Job Details for runs of the affected pipeline, potentially allowing them to perform arbitrary actions within the victim's browser context rather than their own. This issue has been fixed in GoCD 23.1.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.
