EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.6%, top 52% 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.

Authorization Bypass Through User-Controlled Key (CWE-639) in the Excel import handlers (CustomerImport, LeadImport, ProductImport) in Roskus Prospero Flow CRM before 5.14.0 allows a remote, authenticated user of any role or company to create customer, lead, and product records inside another company's tenant via a spreadsheet whose company_id column points to the victim tenant, uploaded to POST /customer/import/excel/save, which maps company_id directly from the file and performs no check that it matches the authenticated user's company.
