A fixed version is listed under Patch Availability — apply it.

ApostropheCMS is an open-source Node.js content management system. Versions up to and including 4.29.0 have a password reset flow that constructs the reset URL using req.hostname, which is derived directly from the attacker-controlled HTTP Host header when apos.baseUrl is not explicitly configured. An unauthenticated attacker who knows a victim's email address can send a crafted reset request that causes the application to email the victim a reset link pointing to the attacker's domain. When the victim clicks the link, the valid reset token is delivered to the attacker, enabling full account takeover. As of time of publication, no known patched versions are available.
