CVE-2026-7232
HighCVSS 7.2Exploitation Probability (EPSS)
Low risk27th percentile - higher than 27% of all known CVEs
Summary
The FormCraft plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 3.9.14 due to insufficient input sanitization and output escaping. Unauthenticated attackers can inject arbitrary web scripts that execute whenever a user accesses an injected page. The exploit chain combines a server-side gap (matrix sub-field keys are not sanitized) with a client-side gap (DOMPurify is only invoked for strings, but matrix values are arrays).
Risk Assessment
An unauthenticated attacker can inject malicious scripts that execute in users' browsers, potentially leading to session theft, redirects, or other attacks.
Recommendation
Update the FormCraft plugin to the latest available version that fixes this vulnerability and implement proper input sanitization and output escaping.

Original NVD description (English source)
The FormCraft plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the '[parameter name]' parameter in all versions up to, and including, 3.9.14 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. The exploit chain combines a server-side gap — where composite matrix sub-field keys such as field2_0 and field2_1 are never passed through the sanitization loop and are stored raw via $wpdb->insert() — with a client-side gap where DOMPurify is only invoked when typeof field.value === 'string', but matrix values arrive from the server as arrays, bypassing the check before being mapped to strings and injected into the DOM. Additionally, the same sink is reachable via a second attack vector: array-typed field values are passed through htmlentities() on submission but later reversed by html_entity_decode() at formcraft-main.php:2608 and :2122, restoring the malicious payload before storage and rendering.
