Avoid dynamic code execution
Summary
The system should not use dynamic code execution features such as eval().
Description
Dynamic code execution features, despite the flexibility they provide, should be used carefully and generally avoided. These features often open the door for remote code execution (RCE) and cross-site scripting (XSS) attacks. Therefore, if it is not possible to avoid dynamic code execution, any untrusted input being included (e.g., the one provided by the users) should be properly sanitized.
