Kroki before 0.36.0 contains a reflected cross-site scripting vulnerability in the /dbml/svg endpoint that allows unauthenticated attackers to inject javascript: hyperlinks by supplying crafted DBML table url, headercolor, or TableGroup color settings. Attackers can send a crafted SVG link that, when opened and the table header clicked, executes attacker JavaScript in the Kroki origin.
