CVE-2026-12427: falha de alta gravidade em ARforms

The ARforms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'description' parameter in all versions up to, and including, 7.2.4 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 injected payload is deserialized via maybe_unserialize() when an administrator views the affected entry; if the attacker's array contains a 'referrer' key, the attacker-controlled page_url and http_referrer values are used as-is and rendered unescaped into the admin entry detail view.
