Published Nov 19, 2025CWE-352EPSS 0.20%

Overview

CVE-2025-12535 is a medium-severity vulnerability. It was published on November 19, 2025 and has a CVSS 3.1 base score of 5.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.3, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
