WordPress 的 Avada (Fusion) Builder 插件在所有版本（包括 7.16.1 及之前版本）中存在授权绕过漏洞。该漏洞源于插件在分发 WordPress 动作钩子（action hook）之前，未正确验证授权。该钩子的名称取自攻击者通过表单字段提供的值（具体通过通知中的 字段占位符和 动态数据令牌实现）。 问题在于：7.16.1 版本中的信任门控函数 仅检查 或 ，而从未检查 。然而，公共的表单提交端点解析的正是 数据，导致授权验证被绕过。 这使得未认证的攻击者能够触发任意的 WordPr

Vulnerability Title
Avada (Fusion) Builder <= 7.16.1 - Unauthenticated Arbitrary WordPress Action Invocation via '{action_hook}' Dynamic-Data Token in Form Field
来源: CVE Program / CVE List V5
Vulnerability Description
The Avada (Fusion) Builder plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 7.16.1. This is due to the plugin not properly verifying authorization before dispatching a WordPress action hook whose name is taken from an attacker-supplied form-field value (via the notification email_message [field] placeholder and the {action_hook,...} dynamic-data token; the 3.16.1 trust gate is_content_request_supplied() only inspects $_POST['args']/$_GET['args'], never the $_POST['formData'] the public form-submit endpoint parses). This makes it possible for unauthenticated attackers to invoke arbitrary WordPress action hooks (multiple per request), causing state changes up to permanent, irreversible destruction of site content: a verified unauthenticated request permanently deleted trashed posts, pages, and comments via the core wp_scheduled_delete action. Other non-deny-listed hooks extend the impact to denial of service (e.g. wp_maybe_auto_update) and, where vulnerable third-party handlers are installed, further privileged writes. The same unauthenticated dynamic-data pipeline additionally exposes a blind arbitrary user/post-meta read; the read result is delivered only to the site owner and is not attacker-exfiltrable through the plugin's own email/response paths. Exploitation requires a published Avada form with AJAX submission and a notification whose email_message template includes an [all_fields] or explicit [field] placeholder - the default form configuration.
