CVE-2024-27937Public exploitNetwork attack vector

Authenticated email disclosure via cross-entity dropdown enumeration

Published Mar 18, 2024 · Updated Aug 2, 2024

Improper authorization in GLPI 10.0.0 through 10.0.12 allows remote authenticated users to obtain every user's email address. Dropdown AJAX handlers trust caller-supplied entity_restrict values instead of intersecting them with the session's active entities. Any authenticated account that can reach the affected dropdown path can enumerate users across otherwise inaccessible entities, disclosing email addresses only.
