What an attacker needs
The record does not say what access is needed yet. Assume the worst until it is scored: treat it as reachable by anyone who can load your site.
What to do now
- Replace weMail. A closed plugin gets no updates through WordPress, so this hole stays open.
- Deactivate and delete it once you have a replacement (Plugins → Deactivate → Delete). Deactivating alone leaves its files on the server.
- Not sure which version you run? Check your version against every known weMail issue.
- If you ran an affected version and something looks off (new admin users, spam pages, redirects), run the free scan below.
The advisory
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.
