CVE-2026-104647 Details
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.
A vulnerability exists in the weMail WordPress plugin in versions through 2.1.6, where the plugin fails to properly verify user capabilities in its REST API permission checks. The plugin incorrectly grants authorization to users with roles listed in the plugin's allowed-roles list (Editor and above by default) for all actions. This flaw enables these users to execute administrator-level tasks, such as enumerating all registered users along with their email addresses and altering the plugin's access-control settings.
