Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-200.

Summary

The weMail WordPress plugin through 2.1.6 does not restrict a site-wide third-party email-service API key to administrators. Users with the Editor role can reach an admin screen that exposes the key, so an attacker with Editor access can obtain a reusable credential that works without a WordPress session. That credential can be used to impersonate other users and sever the site's email-service connection. The flaw is tracked as CWE-200, exposure of sensitive information to an unauthorized actor, and a public exploit link is listed in the references.

Description from the CNA

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.
