The public endpoint ‘customer/check’ could allow an authenticated attacker to enter a telephone number or an email address. When the value entered belongs to a registered customer, the service returns the associated information (email address and telephone number). No authentication is required beyond a static bearer token, and there is no rate limiting or generic error handling. Successful exploitation of this vulnerability could allow a remote attacker to enumerate a user’s contact details, although this would require obtaining a valid static bearer token, constituting an information disclosure vulnerability.","published":"2026-09-14T13:17:33.290","modified":"2026-09-14T13:17:33.290","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://www.incibe.es/en/incibe-cert/notices/aviso/inadequate-access-control-hiperdino-rest-api"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-14T13:17:33.290"}}
