Vulnerabilidades

The parsejson module is vulnerable to regular expression denial of service when untrusted user input is passed into it to be parsed.

unicode-json is a unicode lookup table. unicode-json before 2.0.0 downloads data resources over HTTP, which leaves it vulnerable to MITM attacks.

In jsonwebtoken node module before 4.2.2 it is possible for an attacker to bypass verification when a token digitally signed with an asymmetric key (RS/ES family) of algorithms but instead the attacker send a token digitally signed with a symmetric algorithm (HS* family).

brianleroux tiny-json-http version all versions since commit 9b8e74a232bba4701844e07bcba794173b0238a8 (Oct 29 2016) contains a Missing SSL certificate validation vulnerability in The libraries core functionality is affected. that can result in Exposes the user to man-in-the-middle attacks.

Array index error in the scanstring function in the _json module in Python 2.7 through 3.5 and simplejson before 2.6.1 allows context-dependent attackers to read arbitrary process memory via a negative index value in the idx argument to the raw_decode function.

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

An elevation of privilege 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…

The is-my-json-valid package before 2.12.4 for Node.js has an incorrect exports['utc-millisec'] regular expression, which allows remote attackers to cause a denial of service (blocked event loop) via a crafted string.

The extractFrom function in Internals/QuotedString.cpp in Arduino JSON before 4.5 allows remote attackers to cause a denial of service (crash) via a JSON string with a \ (backslash) followed by a terminator, as demonstrated by "\\\0", which triggers a buffer overflow and over-read.

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.

The JSON gem before 1.5.5, 1.6.x before 1.6.8, and 1.7.x before 1.7.7 for Ruby allows remote attackers to cause a denial of service (resource consumption) or bypass the mass assignment protection mechanism via a crafted JSON document that triggers the creation of arbitrary Ruby symbols or certain internal objects, as…

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.
