## File Changed: `examples/smart_minion/evalute_aime.py`
Details: The code introduces a new function `evaluate_safe_expression` which uses `eval()`, a potentially dangerous function. While some safety measures are implemented, using `eval()` is generally discouraged due to security risks.
Affected Code Snippet:
```python
def safe_eval(expr):
# Allowed operators
allowed_operators = {'+', '-', '*', '/'}
for character in expr:
if not (character.isdigit() or character in allowed_operators):
raise ValueError("Unsafe character detected")
return eval(expr)
```
Start Line: 248
End Line: 254
-------------
Details: The function `evaluate_safe_expression` is introduced to replace `evaluate_expression`, which is a good practice for improving security. However, the implementation still uses `eval()`, which can be risky.
Affected Code Snippet:
```python
def evaluate_safe_expression(expr, numbers):
def safe_eval(expr):
# Allowed operators
allowed_operators = {'+', '-', '*', '/'}
for character in expr:
if not (character.isdigit() or character in allowed_operators):
raise ValueError("Unsafe character detected")
return eval(expr)
# Convert all numbers to integers
numbers = [int(num) for num in numbers]
# ... (rest of the function)
```

## File Changed: `metagpt/actions/action_node.py`
Details: The code changes improve error handling by replacing assertions with explicit exception raising, which is a good practice.
Affected Code Snippet:
```python
def update_instruct_content(self, incre_data: dict[str, Any]):
if not self.instruct_content:
raise ValueError("instruct_content must be initialized")
origin_sc_dict = self.instruct_content.model_dump()
origin_sc_dict.update(incre_data)
output_class = self.create_class()
self.instruct_content = output_class(**origin_sc_dict)
```

fix: replaced assert with conditional check and exception
Removed the use of assert statement and replaced it with a conditional check and exception handling to ensure the validation logic is preserved while eliminating assert related vulnerabilities.Replace assert statements with control flow
Removing assert statements in favor of control flow to avoid issues in optimized byte code compilation. Handling error cases explicitly using conditional statements.Replace asserts with if conditions in review method
Replace potentially removable 'assert' statements with robust 'if/else' control structures in the 'review' method to ensure app stability in an optimized bytecode environment.Replace assert with try/except in update_instruct_content
Replaced the use of 'assert' with 'try/except' to ensure reliable execution in both optimized and non-optimized Python code.Refactor to remove use of eval and use safe expression evaluation
Replaced eval with a safe expression evaluation using literal_evalRemove eval usage and implement safe expression evaluation
Replaced eval with a safe custom evaluation function using the operator module. This mitigates the security risk associated with using eval on user inputs.Replace assert with explicit error handling in main function
Removed usage of assert statement and replaced it with an explicit if condition check and raised custom error to ensure proper flow even when the optimized bytecode is used.Removed exec usage due to vulnerability
Replaced the insecure use of `exec` with a safer method to prevent code injection vulnerabilities. The exposure of dangerous functions was mitigated by managing specific commands rather than executing arbitrary code.
