Weaknesses
CWE · root cause- CWE-197Numeric Truncation ErrorTruncation errors occur when a primitive is cast to a primitive of a smaller size and data is lost in the conversion.
- CWE-681Incorrect Conversion between Numeric TypesWhen converting from one data type to another, such as long to integer, data can be omitted or translated in a way that produces unexpected values. If the resulting values are used in a sensitive context, then dangerous behaviors may occur.
