CVE-2026-15450— WordPress Nex Forms 路径遍历漏洞

NEX-Forms <= 9.2.3 - Authenticated (Admin+) Arbitrary File Deletion via Path Traversal via 'location' Parameter

The Nex Forms – Ultimate Form Builder – Lite plugin for WordPress is vulnerable to arbitrary file deletion via path traversal in versions up to, and including, 9.2.3. This is due to the delete_file() AJAX handler retrieving a file path from the database and passing it directly to unlink() with no validation (no realpath(), basename(), or allowlist check), combined with the insert_record() AJAX handler that lets the same authenticated user store an arbitrary value in the target 'location' column (wp_kses() only strips HTML tags and does not neutralize path traversal or absolute paths). This makes it possible for authenticated attackers, with admin-level access and above, to delete arbitrary files on the affected site's server, including wp-config. When the plugin's user-level option is configured to something else, this may be exploitable with lower privileges.

对路径名的限制不恰当(路径遍历)

WordPress Nex Forms 路径遍历漏洞

WordPress Nex Forms是WordPress基金会开源的一个表单构建插件。 WordPress Nex Forms 9.2.3及之前版本存在路径遍历漏洞，该漏洞源于delete_file() AJAX处理程序从数据库检索文件路径并直接传递给unlink()函数，且未进行路径验证（未检查realpath、basename或白名单），同时insert_record() AJAX处理程序允许同一认证用户在location列存储任意值，可能导致经过身份验证的攻击者删除服务器上的任意文件，包括wp-c
