A sandbox is a restricted environment for executing Lua code, aimed at stopping access to sensitive data or functions. But, sandboxes can be escaped using various methods, including:

 Loadstring: Using the loadstring function to execute a string as Lua code, potentially bypassing sandbox restrictions.

 Debug library: Exploiting the debug library's functions, like debug.getfenv or debug.setfenv, to access and manipulate the environment.

 Metatable manipulation: Modifying metatables to gain access to restricted functions or data.

 String manipulation: Using string concatenation or other string operations to construct and execute restricted code.

 Table manipulation: Exploiting table weaknesses, like using setmetatable or altering table contents.

To prevent sandbox escape, use a combination of:

 Restricting access: Limiting access to sensitive data and functions.

 Code validation: Verifying and sanitizing user-input code.

 Environment separation: Isolating the sandbox environment from the main environment.

 Disabling dangerous functions: Removing or restricting access to functions like loadstring, debug, and setmetatable.

 Regular security audits: Regularly reviewing and updating sandbox restrictions to prevent newly discovered escape techniques.
