- CVE-2021-4402, 1 Jul 2023
- The Multiple Roles plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.3.1. This is due to missing or incorrect nonce validation on the mu_add_roles_in_signup_meta() and mu_add_roles_in_signup_meta_recently() functions. This makes it possible for unauthenticated attackers to add additional roles to users via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

What to do if you run Multiple Roles
If you run Multiple Roles, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.
If no fixed version exists, consider disabling and removing the plugin or replacing it with a maintained alternative. After dealing with the affected software, check administrator users, unexpected file changes, redirects, unfamiliar pages and security logs for signs that the site may already have been altered.
