What is CVE-2018-1000217?

The cJSON library versions 1.7.3 and earlier are susceptible to a Use After Free vulnerability, which can lead to application crashes, data corruption, or potentially remote code execution (RCE). The vulnerability's exploitability largely hinges on how the application utilizes the cJSON library, particularly if the application exposes a network interface. This could potentially allow attackers to exploit the vulnerability over the network. The issue has been addressed in version 1.7.4 of the library.
