Administrator account creation via unchecked registration metadata
Published Mar 7, 2022 · Updated Aug 2, 2024
Privilege escalation in StylemixThemes MasterStudy LMS before 2.7.6 allows remote attackers to create WordPress administrator accounts. The stm_lms_register AJAX handler accepts profile_default_fields_for_register data and persists its wp_capabilities value without restricting the administrator role. No authentication is required; a page nonce and one crafted registration request are enough to create a privileged WordPress account with full site control.
