Issue being resolved: Security improvement on FieldsParser
Solution description
ast.literal_eval() solves a security and reliability problem that arises when using eval() in Python. It safely parses a string containing only Python literal structures
Changes
Replaced eval(value) with ast.literal_eval(value), which is much safer as it only allows Python literals (strings, numbers, tuples, lists, dicts, booleans, and None) to be parsed.
Potential impacts
None
