Jenkins Dingding JSON Pusher Plugin 2.0 and earlier does not mask access tokens displayed on the job configuration form, increasing the potential for attackers to observe and capture them.

Jenkins Dingding JSON Pusher Plugin 2.0 and earlier stores access tokens unencrypted in job config.xml files on the Jenkins controller where they can be viewed by users with Item/Extended Read permission or access to the Jenkins controller file system.

joaquimserafim/json-web-token is a javascript library use to interact with JSON Web Tokens (JWT) which are a compact URL-safe means of representing claims to be transferred between two parties. Affected versions of the json-web-token library are vulnerable to a JWT algorithm confusion attack. On line 86 of the 'index.js' file, the algorithm to use for verifying the signature of the JWT token is taken from the JWT token, which at that point is still unverified and thus shouldn't be trusted. To exploit this vulnerability, an attacker needs to craft a malicious JWT token containing the HS256 algorithm, signed with the public RSA key of the victim application. This attack will only work against this library is the RS256 algorithm is in use, however it is a best practice to use that algorithm.

Denial of Service in JSON-Java versions up to and including 20230618.  A bug in the parser means that an input string of modest size can lead to indefinite amounts of memory being used.

An issue in hjson-java up to v3.0.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted JSON string.

The json2xml package through 3.12.0 for Python allows an error in typecode decoding enabling a remote attack that can lead to an exception, causing a denial of service.

An issue was discovered in json-c from 20200420 (post 0.14 unreleased code) through 0.15-20200726. A stack-buffer-overflow exists in the auxiliary sample program json_parse which is located in the function parseit.

An issue was discovered jjson thru 0.1.7 allows attackers to cause a denial of service or other unspecified impacts via crafted object that uses cyclic dependencies.

An issue was discovered hjson thru 3.0.0 allows attackers to cause a denial of service or other unspecified impacts via crafted object that uses cyclic dependencies.

An issue was discovered pbjson thru 0.4.0 allows attackers to cause a denial of service or other unspecified impacts via crafted object that uses cyclic dependencies.
