# CVE-2025-12536: SureForms <= 1.13.1 - Missing Authorization to Unauthenticated Sensitive Information Exposure

- Exploited (CISA KEV): no
- Published: 2025-11-13
- CVSS: 5.3 MEDIUM (v3.1)
- EPSS: 0.8% (58th percentile)
- CWE: CWE-359

The SureForms plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.13.1 via the '_srfm_email_notification' post meta registration. This is due to setting the 'auth_callback' parameter to '__return_true', which allows unauthenticated access to the metadata. This makes it possible for unauthenticated attackers to extract sensitive data including email notification configurations, which frequently contain vendor-provided CRM/help desk dropbox addresses, CC/BCC recipients, and notification templates that can be abused to inject malicious data into downstream systems.
