CVE-2026-19871: Roskus Prospero Flow CRM

Critical severity, CVSS 9.3. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Roskus Prospero Flow CRM: before 5.15.9 (fixed in 5.15.9)
