Official description

A remote code execution vulnerability in Apioo Fusio 8.8.3 allows authenticated users with the Developer role to execute arbitrary OS commands by exploiting a PHP-Sandbox allow-list bypass. The sandbox allow-list permits functions that transitively invoke system(), enabling a developer to escape the sandbox and gain OS command execution on the server. An attacker with a Developer-role account can achieve full server compromise.
