CWE
- CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Summary
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.
