CVE-2026-53987

MEDIUM

GLPI 11 < 2.14.4 Tag Plugin Stored Cross-Site Scripting in Kanban Badge Rendering

Title source: cna
STIX 2.1

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.
