CVE-2025-4527Network attack vector

Unauthenticated security bypass via client-side validation

Published May 11, 2025 · Updated Jul 31, 2026

Client-side security enforcement in Dígitro NGC Explorer 3.48.21 and earlier allows remote attackers to bypass server validation. The Password Transmission Handler performs part of its security validation in the client rather than enforcing every check on the server. Exploitation requires no privileges or user interaction but depends on complex, specific conditions; the published impact is limited to protected-information exposure.
