Authorization Bypass Through User-Controlled Key in the payroll module in Roskus Prospero Flow CRM before 5.15.10 allows authenticated users holding the read payroll permission to view the salary and banking details of employees of any other company in the instance, and users holding the create payroll permission to create payroll records attributed to another company's employees, because the listing query is not scoped to the caller's company and the employee identifier is validated for global existence rather than company membership
CVE-2026-19870
This high-severity CVE scores 8.6 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 79% 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).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
