CVE-2023-28855Network attack vector

Unauthorized field writes via missing container permission check

Published Apr 5, 2023 · Updated Feb 10, 2025

Improper authorization in pluginsGLPI Fields before 1.13.1 and 1.20.0 through 1.20.3 allows remote authenticated users to alter custom-field data. The update_fields_values branch in front/container.form.php passed request data directly to updateFieldsValues without checking the active profile's right on the selected container. Any authenticated account could therefore modify fields in containers hidden from its configured profile; the documented consequence is unauthorized data modification, not disclosure or service interruption.
