Vulnerable vs. safe
Flagged by this check
return eval(expr)Passes - the safe pattern
return ast.literal_eval(expr)Why it matters & how to fix it
Untrusted input flows into a dynamic code-execution primitive (eval/exec/compile), enabling arbitrary code execution (CWE-94). Never evaluate user-controlled data as code. Use ast.literal_eval() for literals, or an explicit allow-list dispatch table instead.
