AI-suggested
If you cannot patch yet, restrict network access to the affected component and consider implementing compensating controls such as additional authentication mechanisms or disabling the vulnerable onboarding feature if possible.
Description
Use of Hard-coded Credentials in the human resources component in Roskus Prospero Flow CRM before 5.15.9 allows unauthenticated remote attackers to authenticate as any employee onboarded through the standard flow, knowing only their email address, because the employee save controller falls back to the literal password "changeme" and the onboarding form provides no password field.
