CVE-2026-104648

4.9 mediumEPSS 0.1%

Medium (4.9). EPSS 0.1% estimated probability of exploitation activity in the next 30 days.

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.
