What is CVE-2026-18480?

CVE-2026-18480 is a high-severity missing authorization vulnerability in Unknown SureCart, published on 6 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.

Official 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.

Weakness: CWE-269
