Description

A flaw was found in cJSON. An inefficient algorithmic complexity flaw in the `cJSON_Compare()` function allows a remote attacker to cause a denial of service (DoS). By providing specially crafted, deeply nested JSON (JavaScript Object Notation) objects for comparison, an attacker can consume excessive CPU resources, leading to the application becoming unresponsive for extended periods.
