Vulnerability from github – Published: 2026-05-20 03:31 – Updated: 2026-05-20 03:31

Details

The Word 2 Cash plugin for WordPress is vulnerable to Cross-Site Request Forgery leading to Stored Cross-Site Scripting in versions up to and including 0.9.2. This is due to the complete absence of nonce verification on the settings save handler in the w2c_admin() function, combined with missing input sanitization before storage and missing output escaping when rendering the stored value. The w2c-definitions POST parameter is saved raw via update_option() and later echoed without escaping inside a element. This makes it possible for unauthenticated attackers to forge a request on behalf of a logged-in administrator, storing arbitrary JavaScript payloads that execute in the WordPress admin panel whenever the settings page is visited.

Severity

6.1 (Medium)

Vulnerability from cvelistv5 – Published: 2026-05-20 01:25 – Updated: 2026-05-20 12:06

Title

Word 2 Cash <= 0.9.2 - Cross-Site Request Forgeryto Stored Cross-Site Scripting via Settings Page

Summary

The Word 2 Cash plugin for WordPress is vulnerable to Cross-Site Request Forgery leading to Stored Cross-Site Scripting in versions up to and including 0.9.2. This is due to the complete absence of nonce verification on the settings save handler in the w2c_admin() function, combined with missing input sanitization before storage and missing output escaping when rendering the stored value. The w2c-definitions POST parameter is saved raw via update_option() and later echoed without escaping inside a <textarea> element. This makes it possible for unauthenticated attackers to forge a request on behalf of a logged-in administrator, storing arbitrary JavaScript payloads that execute in the WordPress admin panel whenever the settings page is visited.
