WordPress 插件 FundEngine – Donation and Crowdfunding Platform 在所有不超过 1.8.1 的版本中存在授权绕过漏洞。该漏洞是由于插件未正确验证用户是否有权执行特定操作所致。这使得具有订阅者级别及以上权限的已认证攻击者能够修改任意文章和页面——包括覆盖标题和内容，并通过提供攻击者控制的 post_author 整数值来接管页面所有权，从而绕过 wp_kses_post 的 sanitization（安全净化）机制。 处理程序所需的 wp_rest nonce（

Vulnerability Title
FundEngine <= 1.8.1 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Post Modification via 'campaign_post' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The FundEngine – Donation and Crowdfunding Platform plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.8.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify arbitrary posts and pages — overwriting title and content, and seizing ownership by supplying an attacker-controlled post_author integer that bypasses wp_kses_post sanitization. The wp_rest nonce required by the handler is trivially obtainable by any logged-in user via /wp-admin/admin-ajax.php?action=rest-nonce and therefore does not constitute an authorization barrier.
