GHSA-4jq9-2xhw-jpx7
Summary Java: DoS Vulnerability in JSON-JAVA A denial of service vulnerability in JSON-Java was discovered by [ClusterFuzz](https://google.github.io/clusterfuzz/). A bug in the parser means that an input string of modest size can lead to indefinite amounts of memory being used. There are two issues: (1) the parser bug can be used to circumvent a check that is supposed to prevent the key in a JSON object from itself being another JSON object; (2) if a key does end up being a JSON object then it gets converted into a string, using `\` to escape special characters, including `\` itself. So by nesting JSON objects, with a key that is a JSON object that has a key that is a JSON object, and so on, we can get an exponential number of `\` characters in the escaped string.
