EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 72% 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.

FOSSBilling is a free, open-source billing and client management system. In versions 0.5.6 through 0.7.2, when the "Require Email Confirmation" setting is enabled, a logged-in client with an unverified email address (email_approved = 0) can access all client-area pages (e.g. /client/balance, /client/order/list, /client/invoice) and read real account data, including wallet balances and transaction history. The API-side enforcement correctly restricts unverified clients to only profile-related endpoints, but the page-side enforcement is overly permissive, allowing any request whose path starts with /client. Version 0.8.0 contains a fix. No known workarounds that don't involve modifying the source code are available.
