CVE-2025-55886Public exploitNetwork attack vector

Payment-history disclosure via manipulable user identifier

Published Sep 22, 2025 · Updated Sep 22, 2025

Authorization bypass in ARD GEC en Ligne allows remote authenticated users to read other users' payment histories via its API. The payment-history endpoint accepts the fe_uid query parameter as the target account identifier without enforcing that it matches the authenticated session. Any account can therefore retrieve another user's payment records, while no ability to alter records or disrupt service is reported.
