This vulnerability arises when an application uses methods or functions known to be unsafe—such as `eval()` in Python or JavaScript, or `system()` in C or PHP—especially with user-supplied input. These functions can execute arbitrary code or commands, and if input isn’t strictly controlled, they become a vector for injection attacks or privilege escalation.

Remediation

To mitigate this risk, avoid using dangerous functions entirely when safer alternatives exist. If their use is absolutely necessary, ensure inputs are strictly validated, use allowlists, and isolate execution contexts to limit potential damage.
