Joomla 扩展程序——regularlabs.com——在 Joomla 3.0.1 以下版本的"Users Anywhere"扩展中存在敏感信息泄露给未授权用户的问题。管理员本可配置该扩展以禁止输出用户电子邮件地址或用户名。然而，在受影响的代码中，通过 或 / 标签内传入的属性，可以针对当前渲染动态覆盖这些插件设置。例如，即使“允许输出电子邮件”选项被设为“否”，使用 仍可显示电子邮件地址。此漏洞绕过了个人数据输出配置，但并未绕过另一项独立策略：该策略完全禁止在内容源中使用 Users Anywhere 标签

Vulnerability Title
Joomla Extension - regularlabs.com - Exposure of Sensitive Information to Unauthorized Actor in Users Anywhere extension for Joomla < 3.0.1
Source: CVE Program / CVE List V5
Vulnerability Description
Joomla Extension - regularlabs.com - Exposure of Sensitive Information to Unauthorized Actor in Users Anywhere extension for Joomla < 3.0.1 - An administrator can disable output of user email addresses or usernames in Users Anywhere. In affected code, attributes supplied inside a {user} or [email] / [username] tag can change those plugin settings for that render. For example, [email allow_output_email="1"] can display an email address even when Allow output of email is set to No. This bypasses the personal-data output setting; it does not bypass a separate policy that disallows Users Anywhere tags from the content source altogether.
