CVE-2025-56219

Estado: ModificadaAlta (7.1)—

Incorrect access control in SigningHub v8.6.8 allows attackers to arbitrarily add user accounts without any rate limiting. This can lead to a resource exhaustion and a Denial of Service (DoS) when an excessively large number of user accounts are created.
