In March 2023, the National Institute of Standards and Technology (NIST) published the following security bulletin about a potential uncontrolled recursion issue in json-smart 2.4.8 and earlier versions:

CVE-2023-1370 (© 2023 National Institute of Standards and Technology, available at nvd.nist.gov, obtained on September 7, 2023)

When reaching a ‘[‘ or ‘{‘ character in the JSON input, the code parses an array or an object respectively. The code does not have any limit to the nesting of such arrays or objects. Because 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.
