# WordPress membership plugin: forged requests approve or deny user accounts

The User Registration & Membership plugin for WordPress, up to and including 5.2.8, has a missing nonce check on its bulk user action handler. An unauthenticated attacker can trick a logged-in administrator into clicking a link that approves pending registrations or denies arbitrary user accounts, locking those users out of the site.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed version of the User Registration & Membership plugin in the WordPress admin plugin list, or with `wp plugin get <plugin-slug> --field=version`
- Treat a version of `5.2.8` or lower as exposed

## Fix

- Update the User Registration & Membership plugin to a version later than `5.2.8` (the sources do not name the fixed version: unknown)

## From the sources

The User Registration & Membership – Free & Paid Memberships, Subscriptions, Content Restriction, User Profile, Custom User Registration & Login Builder plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 5.2.8 This is due to missing or incorrect nonce validation on the trigger_bulk_action function. This makes it possible for unauthenticated attackers to force administrators to approve pending user registrations or deny arbitrary user accounts, locking targeted users out of the site via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. An attacker can bypass the earlier nonce check in trigger_query_actions() by supplying an empty new_role parameter, which causes that handler to return early and cede control to the unprotected trigger_bulk_action() handler; the exit() call at the end of that handler additionally prevents WordPress core's own bulk-users nonce validation from executing.
