Official description

Kanboard is project management software that focuses on the Kanban methodology. Prior to version 1.2.46, Kanboard allows password reset emails to be sent with URLs derived from the unvalidated Host header when the application_url configuration is unset (default behavior). This allows an attacker to craft a malicious password reset link that leaks the token to an attacker-controlled domain. If a victim (including an administrator) clicks the poisoned link, their account can be taken over. This affects all users who initiate a password reset while application_url is not set. This issue has been patched in version 1.2.46.
