The RegistrationMagic - User Registration Forms Plugin plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 6.0.9.1. This is due to missing or incorrect nonce validation on the process_request function. This makes it possible for unauthenticated attackers to escalate the privileges of an arbitrary form submitter to administrator by creating a malicious Chronos automation task that is executed via WordPress cron via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

AnalysisAI
Privilege escalation via Cross-Site Request Forgery in the RegistrationMagic WordPress plugin (all versions through 6.0.9.1) lets a remote attacker promote an arbitrary form submitter to administrator by forging a request to the process_request function, which lacks proper nonce validation. The attack plants a malicious Chronos automation task that later runs through WordPress cron, and it succeeds when a logged-in administrator is tricked into clicking an attacker-supplied link. No public exploit identified at time of analysis, and it is not listed in CISA KEV; risk is driven by the plugin's install base and the low technical bar of CSRF.
Technical ContextAI
RegistrationMagic (vendor Metagauss) is a WordPress registration/forms plugin that includes 'Chronos,' an automation/scheduled-task subsystem (see plus/chronos/ service, controller, and task libraries in the plugin source). The root cause is CWE-352 (Cross-Site Request Forgery): the process_request handler does not verify a WordPress nonce, so state-changing operations can be triggered by requests the server cannot distinguish from legitimate ones. Because Chronos tasks execute under WordPress cron with the site's own privileges, a task that assigns an administrator role runs later without the CSRF context, converting a forged front-end request into a durable privilege change.
RemediationAI
Upstream fix available (PR/commit); released patched version not independently confirmed - the WordPress.org trac changeset (revision 3579552) shows the nonce-validation fix, so update the RegistrationMagic plugin to the latest available version above 6.0.9.1 via the WordPress admin plugin updater and confirm the installed version afterward. Until you can update, reduce exposure by restricting who holds administrator sessions and enforcing that admins do not browse untrusted links while authenticated; consider temporarily deactivating the plugin if the Chronos automation feature is not in use, accepting the trade-off that registration forms will be unavailable. A web application firewall (such as Wordfence) can add CSRF/nonce-enforcement rules on the process_request endpoint as a compensating control, with the caveat that generic rules may not cover all task-creation paths. Reference the Wordfence advisory (https://www.wordfence.com/threat-intel/vulnerabilities/id/ef7aff85-e1ca-47ce-86e9-a0fe356993a1?source=cve) for detection signatures and version guidance.
