AI risk analysis

Summary: The flaw allows unauthenticated attackers to register as administrators by exploiting a privilege escalation vulnerability in the Divi Membership plugin for WordPress up to version 2.2.0.
Exploitability: Exploitation requires a WordPress nonce, which is publicly available, making it relatively easy for attackers to exploit the vulnerability.
Blast radius: If exploited, this could result in full site takeover, as attackers can immediately authenticate as an administrator.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to Divi Membership version 2.3.0 or later.

NVD description

The Divi Membership plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 2.2.0. This is due to the `dmem_form_submit_handler()` function determining the new user's role by iterating all WordPress roles and calling `password_verify()` against an attacker-controlled bcrypt hash supplied in the `form_id` POST parameter, with no validation or whitelist of allowed roles. This makes it possible for unauthenticated attackers to register a new account with the administrator role by submitting a locally computed bcrypt hash of `administrator` as `form_id`, and when `auto_login=on` is submitted, be immediately authenticated as that administrator in the same request, resulting in full site takeover. Exploitation requires a WordPress nonce, but that nonce is publicly emitted on any page rendering the Divi Membership registration form and is therefore obtainable by any unauthenticated visitor.
