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 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.

Risk Assessment

An attacker can inject malicious HTML/JavaScript code that executes in other users' browsers, potentially leading to session theft, data leakage, or unauthorized actions within the GLPI system.

Recommendation

Immediately update the Tag plugin to version 2.14.4 or later, which includes security fixes against HTML injection.
