CVE-2022-39376Network attack vector

Custom-field disclosure via crafted mailto links

Published Nov 3, 2022 · Updated Apr 23, 2025

Improper input validation in GLPI before 10.0.4 allows remote authenticated users to disclose custom-field values through crafted mailto links. GLPI inserts attacker-controlled custom-field values into mailto links without sufficient validation; the responsible function is not publicly identified. Low-privileged access and user interaction are required, and the reported consequence is limited to exposure of those field values.
