Pronamic Pay <= 10.1.0 - Authenticated (Subscriber+) Privilege Escalation via Gravity Forms 'Update user role' Field
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.
