脆弱性タイトル
WP HTML Author Bio <= 1.2.0 - Author+ Stored Cross-Site Scripting
ソース: NVD (National Vulnerability Database)
脆弱性説明
The WP HTML Author Bio WordPress plugin through 1.2.0 does not sanitise the HTML allowed in the Bio of users, allowing them to use malicious JavaScript code, which will be executed when anyone visit a post in the frontend made by such user. As a result, user with a role as low as author could perform Cross-Site Scripting attacks against users, which could potentially lead to privilege escalation when an admin view the related post/s.

WordPress 插件 跨站脚本漏洞
ソース: CNNVD (China National Vulnerability Database)
脆弱性説明
WordPress 插件是WordPress开源的一个应用插件。 WordPress 插件 WP HTML Author Bio 1.2.0之前版本存在跨站脚本漏洞，该漏洞源于软件对于用户的HTML缺少有效的验证与转义，允许他们使用恶意JavaScript代码，当任何人访问该用户在前端的帖子时，恶意代码将被执行。因此，角色低至作者的用户可以对用户执行跨站点脚本攻击，这可能导致管理员查看相关帖子时发生权限升级的情况。
