getgrav/grav is vulnerable to Server-side Template Injection (SSTI). An authenticated remote attacker is able to cause server side template injection via the Twig engine which renders risky functions by default, such as system. Insufficient fix in addressing CVE-2022-2073 allows the bypass of the denylist in validation checks.
