CVE-2024-21622Network attack vector

Authenticated privilege escalation via incomplete save authorization

Published Jan 3, 2024 · Updated Apr 17, 2025

Privilege escalation in Pixel & Tonic Craft CMS before 3.9.6 and 4.0.0-RC1 through 4.5.10 allows remote authenticated users to modify protected data. ElementsController applied attacker-controlled POST parameters before checking save authorization, while UsersController accepted a username when an authorized non-admin edited another user. Exploitation requires an authenticated account with a permissions setup that reaches either save path, enabling unauthorized changes without reported data disclosure.
