Problem Description:
The isJSON function returns sometimes true for a given string, that is not correct JSON. If you use isJSON to check for a JSON string and then try to parse that you get unexpected errors.
Steps to Reproduce:
Run the following code:
var a = "-";
if (isJSON(a)) {
var b = deserializeJSON(a); // <====== throws an error! a is not correct JSON
}
I have created a cffiddle to demonstrate the problem. The red line are where CF incorrectly says that the value is a valid JSON, when it is really not valid.

I have validated all the sample values with https://jsonlint.com/ and double checked with the JSON definition at:https://www.json.org/
Workaround:
Always use deserialiseJSON instead of isJSON and put a try/catch around the deserializeJSON() function.Attachments:
