CVE-2025-12535: CWE-352 Cross-Site Request Forgery (CSRF) in brainstormforce SureForms – Contact Form, Payment Form & Other Custom Form Builder
The SureForms plugin for WordPress is vulnerable to Cross-Site Request Forgery Bypass in all versions up to, and including, 1.13.1. This is due to the plugin distributing generic WordPress REST API nonces (wp_rest) to unauthenticated users via the 'wp_ajax_nopriv_rest-nonce' action. While the plugin legitimately needs to support unauthenticated form submissions, it incorrectly uses generic REST nonces instead of form-specific nonces. This makes it possible for unauthenticated attackers to bypass CSRF protection on REST API endpoints that rely solely on nonce verification without additional authentication checks, allowing them to trigger unauthorized actions such as the plugin's own post-submission hooks and potentially other plugins' REST endpoints.
AI Analysis
Technical Summary
CVE-2025-12535 is a medium-severity CSRF vulnerability in the SureForms plugin for WordPress (versions up to 1.13.1). The plugin exposes generic WordPress REST API nonces (wp_rest) to unauthenticated users through the 'wp_ajax_nopriv_rest-nonce' action. Instead of using form-specific nonces, this generic nonce allows attackers to bypass CSRF protections on REST API endpoints that depend solely on nonce validation without additional authentication. This can enable unauthorized triggering of plugin post-submission hooks and potentially affect other plugins using similar nonce mechanisms.
Potential Impact
The vulnerability allows unauthenticated attackers to perform unauthorized actions by bypassing CSRF protections on certain REST API endpoints. It does not affect confidentiality or availability but impacts integrity by enabling unauthorized modifications through the plugin's hooks or other plugins relying on the same nonce approach.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided in the available data. Until a patch is available, users should monitor vendor communications for updates. Since the plugin requires unauthenticated form submissions, additional manual mitigation may be limited. Avoid relying solely on generic REST API nonces for CSRF protection and consider implementing form-specific nonces or additional authentication checks if possible.
