EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 68% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

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.
