DescriptionGitHub Advisory

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. In Coolify versions up to and including v4.0.0-beta.434, an attacker can initiate a password reset for a victim, and modify the host header of the request to a malicious value. The victim will receive a password reset email, with a link to the malicious host. If the victim clicks this link, their reset token is sent to the attacker's server, allowing the attacker to use it to change the victim's password and takeover their account. As of time of publication, it is unclear if a patch is available.
