Technical details
A host header injection vulnerability exists in @perfood/couch-auth versions <= 0.20.0 in the password reset functionality. An attacker sends a specially crafted Host header in a forgot-password request, causing the application to embed a malicious domain in the password reset link sent to users. When a user clicks the link, their password reset token is leaked to the attacker-controlled server. No authentication is required to trigger the vulnerability; user interaction (clicking the link) is necessary. An attacker can subsequently use the stolen token to reset the victim's password and take over their account. The issue affects all versions up to and including 0.20.0.
