Sources and claim methodology

Upstream source description

The Tag plugin for GLPI 11 before 2.14.4 stores the tag name without HTML sanitization and renders it into the Kanban badge markup via PluginTagTag::preKanbanContent() without output escaping, resulting in stored cross-site scripting. An authenticated user with TAG MANAGEMENT create or update rights can set a tag name containing HTML, which then executes in the browser of any user who opens the Kanban view of a ticket, problem, change, or project the tag is attached to.
