Stored script execution via ITIL cost payloads
Published Jun 2, 2026 · Updated Jun 2, 2026
Stored XSS in GLPI 11.0.0 through 11.0.6 allows remote authenticated users with technician access to execute script through ITIL costs. The ITIL cost workflow persists a technician-supplied XSS payload, but the vendor has not disclosed the affected handler or precise neutralization failure. Exploitation requires technician privileges and active interaction by another user, allowing script to run in that viewer's GLPI session context.
