CVE-2026-104647 weMail <= 2.1.6 - Editor+ Incorrect Authorization via User::can()
Description
The weMail WordPress plugin through 2.1.6 does not correctly verify user capabilities in its REST API permission checks, treating any user whose role is in the weMail WordPress plugin through 2.1.6's allowed-roles list (Editor and above by default) as authorised for every action, which allows such users to perform administrator-level actions including enumerating all registered users with their email addresses and modifying the weMail WordPress plugin through 2.1.6's own access-control configuration.
