WordPress 插件 GiveWP（捐赠插件与筹款平台）在所有 4.19.1 及以下版本中存在权限提升漏洞，攻击面涉及 参数。该漏洞的成因在于： 函数仅对字符串 执行了狭窄的字面量检查，而未在保存时强制应用插件自身的 白名单；同时， AJAX 处理器在导入 JSON 时，直接通过 将数据写入 选项，完全未调用任何清理（sanitize）过滤器。 这使得拥有 GiveWP 管理器角色（具备 权限）或更高权限的已认证攻击者能够配置捐赠者注册功能，将高级 WordPress 角色（最高可达管理员角色）分配给通过该平台

Vulnerability Title
GiveWP <= 4.19.1 - Authenticated (Custom+) Privilege Escalation to 'donor_default_user_role' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.19.1 via the `donor_default_user_role` parameter. This is due to the `sanitize_option_donor_default_user_role()` function applying only a narrow literal check against the string `'administrator'` rather than enforcing the plugin's own `give_get_donor_safe_user_roles()` allowlist on save, and due to the `give_core_settings_import_callback()` AJAX handler writing imported JSON directly into the `give_settings` option via `update_option()` without invoking the sanitize filter at all. This makes it possible for authenticated attackers with the GiveWP Manager role (holding the `manage_give_settings` capability) and above to configure donor registration to assign privileged WordPress roles — up to and including Administrator via the import path — to every new donor account created through the platform. Via the settings save path, the Administrator role is blocked but any other elevated role (Editor, Author, etc.) is accepted; via the Tools › Import JSON path, the sanitize filter is bypassed entirely, allowing the Administrator role itself to be stored and subsequently applied to all newly registered donor accounts.
