Description (CNA)
Discourse is an open-source discussion platform. From versions 2026.1.0-latest to before 2026.1.4, 2026.3.0-latest to before 2026.3.1, and 2026.4.0-latest to before 2026.4.1, group owners who are not necessarily admins or moderators can view a group's outgoing email/SMTP credentials in plaintext via the group history log (/groups/:name/logs.json). Affected fields: email_password, email_username, smtp_server, smtp_port, smtp_ssl_mode. The most sensitive item is the SMTP password, which an owner could use to send mail as the group from outside Discourse. This impacts sites that have configured per-group SMTP credentials and granted group ownership to users who should not have access to those credentials. This issue has been patched in versions 2026.1.4, 2026.3.1, 2026.4.1, and 2026.5.0-latest.1.
