CVE-2026-262657.5

This vulnerability allows an attacker to access private user information, such as phone numbers and addresses, from all users in a Discourse forum, even if they are not logged in. It occurs because the system does not properly check permissions for certain user data fields, making it easy for anyone to exploit this flaw and collect sensitive information.
