CVE-2025-54816: Evmapa missing authentication for critical function vulnerability
Evmapa · Evmapa
This vulnerability occurs when a WebSocket endpoint does not enforce proper authentication mechanisms, allowing unauthorized users to establish connections. As a result, attackers can exploit this weakness to gain unauthorized access to sensitive data or perform unauthorized actions. Given that no authentication is required, this can lead to privilege escalation and potentially compromise the security of the entire system.
