Forminator Forms: Privilege escalation via payment-gated registration form
Summary
Forminator Forms, a WordPress form plugin, does not enforce payment on the server side when the form's configured payment gateway is unavailable. Unauthenticated visitors can complete a payment-gated user registration form without paying and receive the form's configured role, up to administrator. The flaw is described as occurring after the gateway has been connected and later disconnected, so it requires a payment-gated registration form with a role assignment.
Affected
- Forminator Forms 1.58.0 to before 1.58.4 (according to the CNA record)
- Versions before 1.58.0: Unknown.
Fixed in
- Forminator Forms 1.58.4
Workaround
- No vendor workaround documented.
- Interim measure (not from a vendor source): unpublish registration forms that combine a payment field with a role assignment until the plugin is updated.
- Review the default role of each registration form.
Exploitation
- Not known to be exploited in the wild.
- Not listed in CISA KEV.
- CISA SSVC: exploitation none, automatable no, technical impact total.
- No public proof-of-concept found in the sources checked. The WPScan reference is tagged as exploit and should be checked directly.
Our recommendation
- Update Forminator Forms to 1.58.4 or later on every site, even if the plugin is rarely used.
- Review payment-gated registration forms and their assigned roles.
- Review recently created administrator accounts for unknown users.
- Monitor new user registrations for elevated roles.

PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
