CVE-2024-52947Network attack vector

Browser script execution via unchecked upgrade URL

Published Nov 18, 2024 · Updated Nov 3, 2025

Cross-site scripting in LemonLDAP::NG before 2.20.1 allows remote authenticated users to inject script through the upgrade URL. The Upgrade plugin passes untrusted url and forceUpgrade values to its confirmation form without calling the portal XSS filter. An administrator must enable the plugin, and a user must open the crafted request before attacker-controlled code runs in the portal origin.
