CVE-2026-18480

SureCart < 4.6.3 - Subscriber+ Administrator Account Takeover

Published Sep 6, 2026 CVSS 3.1 · 8.8 High EPSS < 1% KEV · Not listed
Description
The SureCart WordPress plugin before 4.6.3 does not ensure that the account affected by a customer update is the same account its permission check authorised, allowing users with a subscriber-level account to change another user's email address, including an administrator's, and take over that account via a password reset. It further allows an attacker-controlled customer record to be associated with an arbitrary user, and discloses customer identifiers and email addresses to any authenticated user, which together make the takeover reachable from a subscriber-level account alone.
