{"id":"CVE-2026-53642","state":"PUBLISHED","title":"FOSSBilling: Unverified clients can access client-area pages when email confirmation is required","description":"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.","publishedAt":"2026-07-06T22:45:51.137Z","updatedAt":"2026-07-07T14:27:05.224Z","severity":{"score":5.3,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["FOSSBilling FOSSBilling"],"affected":[{"vendor":"FOSSBilling","product":"FOSSBilling","versions":[{"version":">= 0.5.6, < 0.8.0","status":"affected"}]}],"references":["https://github.com/FOSSBilling/FOSSBilling/security/advisories/GHSA-7v47-rh46-w923"],"weaknesses":["CWE-863"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/53xxx/CVE-2026-53642.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-53642","state":"PUBLISHED","datePublished":"2026-07-06T22:45:51.137Z","dateUpdated":"2026-07-07T14:27:05.224Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-09T20:16:59.648Z"},"containers":{"cna":{"title":"FOSSBilling: Unverified clients can access client-area pages when email confirmation is required","descriptions":[{"lang":"en","value":"FOSSBilling is a free, open-source billing and client management system.
