Dave Gamble cJSON version 1.7.6 and earlier contains a CWE-772 vulnerability in cJSON library that can result in Denial of Service (DoS). This attack appear to be exploitable via If the attacker can force the data to be printed and the system is in low memory it can force a leak of memory. This vulnerability appears to have been fixed in 1.7.7.

Dave Gamble cJSON version 1.7.3 and earlier contains a CWE-416: Use After Free vulnerability in cJSON library that can result in Possible crash, corruption of data or even RCE. This attack appear to be exploitable via Depends on how application uses cJSON library. If application provides network interface then can be exploited over a network, otherwise just local.. This vulnerability appears to have been fixed in 1.7.4.

An elevation of privilege vulnerability exists when the ASP.NET Core fails to properly sanitize web requests.

A spoofing vulnerability exists when the ASP.NET Core fails to properly sanitize web requests.

A denial of service vulnerability exists when the ASP.NET Core fails to properly validate web requests. NOTE: Microsoft has not commented on third-party claims that the issue is that the TextEncoder.EncodeCore function in the System.Text.Encodings.Web package in ASP.NET Core Mvc before 1.0.4 and 1.1.x before 1.1.3 allows remote attackers to cause a denial of service by leveraging failure to properly calculate the length of 4-byte characters in the Unicode Non-Character range.

The hash functionality in json-c before 0.12 allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted JSON data, involving collisions.

Buffer overflow in the printbuf APIs in json-c before 0.12 allows remote attackers to cause a denial of service via unspecified vectors.

Dan Pascu python-cjson 1.0.5 does not properly handle a ['/'] argument to cjson.encode, which makes it easier for remote attackers to conduct certain cross-site scripting (XSS) attacks involving Firefox and the end tag of a SCRIPT element.

Buffer overflow in Dan Pascu python-cjson 1.0.5, when UCS-4 encoding is enabled, allows context-dependent attackers to cause a denial of service (application crash) or possibly have unspecified other impact via vectors involving crafted Unicode input to the cjson.encode function.
