CVE-2026-26063Network attack vector

Unauthorized transactions via transaction API validation bypass

Published Feb 19, 2026 · Updated Feb 19, 2026

Improper input validation in CediPay before 1.2.3 allows remote attackers to alter transactions through the transaction API. The advisory identifies the transaction API as the affected locus but does not disclose which fields or validation checks accept untrusted values. Network access to the API requires no authentication or user interaction; successful exploitation compromises financial-data confidentiality and transaction integrity without interrupting service.
