CVE-2026-12142
HighCVSS 7.2Summary
The NEX-Forms plugin for WordPress up to version 9.2.2 is vulnerable to Stored Cross-Site Scripting via the '_name[]' array parameter. Insufficient input sanitization and output escaping allow unauthenticated attackers to inject arbitrary scripts that execute when a user accesses the affected page.
Risk Assessment
An attacker can inject malicious scripts that execute in the browsers of administrators and users, potentially leading to session theft, account takeover, or further malware distribution.
Recommendation
Immediately update the NEX-Forms plugin to the latest available version that fixes this vulnerability. If no update is available, temporarily disable the plugin.
Original NVD description (English source)
The NEX-Forms – Ultimate Forms Plugin for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via '_name[]' Array Parameter in all versions up to, and including, 9.2.2 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 wp_kses() output filtering pass provides no mitigation because NEXForms_allowed_tags() explicitly permits <script>, <iframe src/srcdoc>, and JS event handlers such as onClick, onBlur, and onChange in its allow-list.
