16th percentile - higher than 16% of all known CVEs

Summary

The Database for CF7 plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Array Form Field Values in all versions up to, and including, 1.2.6 due to insufficient input sanitization and output escaping. Unauthenticated attackers can inject arbitrary web scripts that execute when a user accesses an injected page. This is exploitable because Contact Form 7 accepts array-structured input for ordinary text fields via the public REST API endpoint, and the plugin stores submitted data using $wpdb INSERT with serialize() into a custom table, bypassing WordPress save-time filtering.

Risk Assessment

An attacker can inject malicious scripts that execute in administrators' and users' browsers, leading to session theft, defacement, or further attacks.

Recommendation

Update the Database for CF7 plugin to the latest version that fixes this vulnerability, and consider using alternative form data storage methods.

Original NVD description (English source)

The Database for CF7 plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Array Form Field Values in all versions up to, and including, 1.2.6 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable by unauthenticated attackers because Contact Form 7 accepts array-structured input for ordinary text fields (e.g., your-name[]) via the public REST API endpoint /wp-json/contact-form-7/v1/contact-forms/{id}/feedback, and the plugin stores submitted data using $wpdb INSERT with serialize() into a custom wp_cf7db table, bypassing WordPress save-time filtering via wp_insert_post/wp_kses.
