Wemail CVEs and Security Vulnerabilities

CVE-2026-104648

weMail <= 2.1.6 - Editor+ API Key Disclosure

The weMail WordPress plugin through 2.1.6 does not restrict a site-wide third-party email-service API key to administrators, exposing it in an admin screen that users with the Editor role can reach by default, which allows them to obtain a reusable credential usable without a WordPress session to impersonate other users and sever the site's email-service connection.

CVE-2026-104647

weMail <= 2.1.6 - Editor+ Incorrect Authorization via User::can()

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.
