Jenkins contains a stored cross-site scripting vulnerability in the handling of a node's generic offline cause description. Since Jenkins 2.483, offline cause descriptions for nodes are treated as HTML and rendered as such. In Jenkins 2.483 through 2.567 inclusive, and Jenkins LTS 2.492.1 through 2.555.2 inclusive, user-supplied offline cause content that can be set via the POST config.xml API is not properly escaped before being rendered in the UI. An attacker with Agent/Configure permission can submit a malicious offline cause payload in an agent configuration, causing attacker-controlled script to be stored server-side and later executed in the browser of a user who views the affected agent's status page. Jenkins tracks this issue as SECURITY-3731.
