CVE-2022-35945Network attack vector

Administrator session theft via unescaped registration metadata

Published Sep 14, 2022 · Updated Apr 23, 2025

Stored cross-site scripting in GLPI 9.5.0 through 10.0.2 allows remote attackers to steal an administrator session cookie. GLPINetwork::showForConfig() writes the registration API's validation message, subscription title, and owner name into HTML without encoding special characters. Exploitation requires an administrator to configure an attacker-created registration key and open its configuration page, where injected script runs in the administrator's browser.
