CVE-2026-23489Network attack vector

Authenticated PHP code execution via generated dropdown classes

Published Mar 16, 2026 · Updated Mar 16, 2026

Code injection in GLPI Fields before 1.23.3 allows remote authenticated users with dropdown-creation rights to execute arbitrary PHP. PluginFieldsDropdown::create interpolates unsanitized field names and labels into PHP class templates, writes the generated classes to disk, and invokes them. A GLPI account permitted to create dropdowns can supply PHP syntax that runs with the web application's server privileges.
