Overview
Affected versions of this package are vulnerable to Incorrect Authorization via the PATCH /server/{id} process. An attacker can gain unauthorized access to another user's DDNS profile context by storing a nonexistent ddns_profiles ID for a server they own, which is later resolved if another user creates a DDNS profile with that ID.
