{"id":"CVE-2026-12258","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-12258","generatedAt":"2026-09-20T15:57:43.081Z","title":"The public endpoint ‘customer/check’ could allow an authenticated attacker to enter a telephone number or an email address.","description":"Inadequate access control in Hiperdino’s REST v1.0 API. 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":"2026-09-14T13:17:33.000Z","lastModified":"2026-09-18T19:21:49.000Z","status":"Deferred","sourceIdentifier":"cve-coordination@incibe.es","cvss":{"version":"4.0","score":9.2,"severity":"CRITICAL","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-284"],"affected":[],"epss":{"score":0.004,"percentile":0.34024,"date":"2026-09-19","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.40%).
