Summary

The Pronamic Pay plugin for WordPress is vulnerable to privilege escalation. The `maybe_update_user_role()` function passes a Gravity Forms field value directly to `WP_User::set_role()` without validation, allowing authenticated attackers with Subscriber-level access to change their role to Administrator.

Risk Assessment

An authenticated attacker can gain full control of the site by escalating their privileges to administrator.

Recommendation

Update the Pronamic Pay plugin to a version that introduces an allowlist of roles and permission checks.

Original NVD description (English source)

The Pronamic Pay plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 10.1.0 This is due to the `maybe_update_user_role()` function passing an attacker-controlled Gravity Forms field value (`$lead[$feed->user_role_field_id]`) directly into `WP_User::set_role()` without any allowlist validation, capability comparison, or permission check to constrain which roles can be assigned. This makes it possible for authenticated attackers, with Subscriber-level access and above, to escalate their own WordPress account to Administrator by tampering with the role field value in a form submission. Exploitation requires that an administrator has already configured a Pronamic Pay payment feed in Gravity Forms with the **Update User Role** option enabled and mapped to a form field; once that configuration is in place, no further preconditions exist to prevent an authenticated attacker from exploiting this vulnerability.
