Concrete CMS has a session-hardening bypass and allows password change without reauthorization

Published May 22, 2026·Updated Jun 24, 2026

NVD Description

Concrete CMS 9.5.0 and below is vulnerable to password change without reauthorization and session-hardening bypass. The user-profile edit controller passes the entire raw POST array to UserInfo::update() without field whitelisting resulting in password change without requiring the current password  and also resulting in registered users able to disable the per-user-IP-pinning in the session validator which is meant to detect hijacking.

Affected Packages (1)

concrete5/concrete5COMPOSER
Fixed in 9.5.1
