JSONata is a JSON query and transformation language. Prior to 2.2.0 and 1.8.9, malicious non-matching inputs to the $toMillis function can cause superlinear backtracking in the ISO-8601 validation regex, leading to denial of service in applications that evaluate user-provided JSONata expressions. This issue is fixed in version 2.2.0 and 1.8.9.
