  "details": "Cross-site request forgery in the REST API of Progressive Robot hMailServer 6.0.0 through 6.3.6 allows a remote attacker to make an authenticated user's browser perform a state-changing request. The REST API accepts HTTP Basic authentication and answers a browser with a Basic sign-in box; a browser caches the credential once the box is answered and sends it with later requests to that origin, including a top-level form post from another site, and the server reads a request body whatever its declared content type. The cross-site protection covered only the cookie session (a header a cross-site form cannot set, and a SameSite=Strict cookie); HTTP Basic was not held to it. A page under an attacker's control, visited by a user whose browser holds a cached Basic credential for the REST API - typically an administrator who signed in through the box - could therefore cause a state-changing request such as creating a domain, an account or an API key, or changing a setting, with the victim's credential. The attacker cannot read the cross-origin response, so the forgery is blind.",
