CVE-2026-1934Network attack vector

Authenticated payment bypass via unchecked user meta write

Published May 12, 2026 · Updated May 12, 2026

Missing authorization in StylemixThemes Motors 1.4.103 and earlier allows remote authenticated users to bypass dealer payments. The stm_save_user_extra_fields() profile handler writes POSTed stm_payment_status user meta after checking only edit_user, which permits self-profile edits. Subscriber-level access is sufficient to set the value to completed and obtain paid Dealer membership features without a PayPal transaction.
