# CVE-2026-102801: Joomla Extension - regularlabs.com - Exposure of Sensitive Information to Unauthorized Actor in Users Anywhere extension for Joomla < 3.0.1

Status: published. Published: 2026-11-02. Updated: 2026-11-02.

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.
