Hi,

The following vulnerability was published for json-smart.

CVE-2023-1370[0]:
| [Json-smart](https://netplex.github.io/json-smart/) is a performance
| focused, JSON processor lib. When reaching a &#8216;[&#8216;
| or &#8216;{&#8216; character in the JSON input, the code
| parses an array or an object respectively. It was discovered that the
| code does not have any limit to the nesting of such arrays or objects.
| Since the parsing of nested arrays and objects is done recursively,
| nesting too many of them can cause a stack exhaustion (stack overflow)
| and crash the software.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
