Name of the Vulnerable Software and Affected Versions
FOSSBilling versions 0.5.6 through 0.7.2
Description
When the Require Email Confirmation setting is enabled, a logged-in client with an unverified email address, indicated by the variable
email approved = 0, can bypass page-side enforcement. This allows the user to access all client-area pages, such as the /client/balance, /client/order/list, and /client/invoice endpoints, and read sensitive account data, including wallet balances and transaction history. While the API correctly restricts unverified clients to profile-related endpoints, the page-side enforcement is overly permissive for any request path starting with /client.Recommendations
Update FOSSBilling to version 0.8.0.
