10Web Booster 是一款用于 WordPress 的网站速度优化、缓存及页面速度优化插件。在其所有不高于 2.34.10 的版本中，存在任意文件上传漏洞，该漏洞可通过 compressCustom 函数触发。问题源于对 page_id 参数缺少文件类型验证和扩展名过滤，同时由于泄露的 nonce（随机数）具有全局可读权限，从而绕过了身份验证检查。这使得未授权的攻击者能够上传可执行文件，进而可能导致远程代码执行。此漏洞利用链需要获取插件的 REST nonce（tenwebio_rest）。当批量优化任务暂

Vulnerability Title
10Web Booster <= 2.34.10 - Unauthenticated Arbitrary File Upload via 'page_id' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The 10Web Booster – Website speed optimization, Cache & Page Speed optimizer plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 2.34.10 via the compressCustom function. This is due to missing file type validation and extension filtering on the page_id parameter, combined with a world-readable leaked nonce that bypasses authentication checks. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible. This exploit chain requires obtaining the plugin's REST nonce (tenwebio_rest), which is automatically serialized to a world-readable file under wp-content/uploads/ whenever a bulk optimisation batch pauses; because the nonce is generated in a cron/loopback context with a user ID of 0, it is valid for unauthenticated visitors.
