A security issue was found in Netplex Json-smart 2.5.0 through 2.5.1. When loading a specially crafted JSON input, containing a large number of ’{’, a stack exhaustion can be trigger, which could allow an attacker to cause a Denial of Service (DoS). This issue exists because of an incomplete fix for CVE-2023-1370.
The fixed version only addresses the default modes provided by JSONParser, such as MODE_RFC4627. If you create the JSONParser manually or with custom options, make sure to set the LIMIT_JSON_DEPTH option.
