DescriptionCoolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.471, the TrustProxies middleware trusts all proxies ($proxies = '*'), accepting X-Forwarded-Host from any source. The TrustHosts middleware, intended to prevent host header attacks, has a circular caching dependency that prevents it from ever validating hosts. When a password reset is requested, the ResetPassword notification generates the reset URL using url(route(..., false)), which derives the host from the (spoofable) request. An unauthenticated attacker can trigger a password reset email containing a link pointing to an attacker-controlled domain, enabling token theft and account takeover. This issue is fixed in version 4.0.0-beta.471.
