{"id":"CVE-2026-53642","summary":"FOSSBilling: Unverified clients can access client-area pages when email confirmation is required","details":"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.","aliases":["GHSA-7v47-rh46-w923"],"modified":"2026-08-07T11:50:20.146906958Z","published":"2026-07-06T22:45:51.137Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53642.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53642.json"},{"type":"ADVISORY","url":"https://github.com/FOSSBilling/FOSSBilling/security/advisories/GHSA-7v47-rh46-w923"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53642"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/fossbilling/fossbilling","events":[{"introduced":"54743baa65ddfc6ea473ece7e4e860e977c31393"},{"fixed":"3bd35f5b2921d8a26a403142ae0408f95e6463cc"}],"database_specific":{"extracted_events":[{"introduced":"0.5.6"},{"fixed":"0.8.0"},{"fixed":"0.7.2"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53642.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V4","score":"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"}]}
