CVE-2026-53642 Details
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.
A vulnerability in FOSSBilling versions 0.5.6 through 0.7.2 allows logged-in clients with unverified email addresses to bypass access restrictions and view sensitive account information. This issue arises when the 'Require Email Confirmation' setting is enabled. While the API correctly limits unverified clients to profile-related endpoints, the web application improperly allows access to all client-area pages, including balance, order lists, and invoices. The vulnerability was introduced in version 0.5.6 and patched in 0.8.0.
Users can upgrade to FOSSBilling version 0.8.0, which addresses this vulnerability.
