Unauthenticated role escalation via unchecked membership level
Published Mar 5, 2026 · Updated Mar 5, 2026
Privilege escalation in StellarWP Kadence Memberships 3.2.20 and earlier allows remote attackers to obtain privileged WordPress roles. The rcp_setup_registration_init() function trusts the rcp_level POST value without checking that the selected level is active or paid, while add_user_role() assigns that level's configured role without a status check. No authentication is required, but a site must expose registration and contain a selectable membership level mapped to a privileged role.
