CVE-2026-16635 is a privilege escalation vulnerability in the Pronamic Pay plugin for WordPress affecting all versions up to and including 10.1.0. The flaw is in the maybe_update_user_role() function, which passes an attacker-controlled Gravity Forms field value directly to WP_User::set_role() when processing a configured payment feed. Because the role value is not constrained by an allowlist and is not subject to capability validation or permission checks, a low-privileged authenticated user can supply an arbitrary role value and cause their own account role to be reassigned. In deployments where an administrator has configured a Pronamic Pay Gravity Forms payment feed with the Update User Role option enabled and mapped to a form field, an attacker with Subscriber-level access or higher can tamper with the submitted role field and elevate their account to Administrator.
