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.

GHSA-86vw-mfpg-wwv9 — jsonata: Malicious inputs to "$toMillis" function can cause resource exhaustion

2026-10-08T10:57:35.209274+00:00

Affected: npm: jsonata

### Impact Before JSONata `2.2.0` and `1.8.9`, it is possible to craft non-matching inputs to the [$toMillis](https://docs.jsonata.org/date-time-functions#tomillis) function that cause superlinear backtracking in the ISO-8601 validation regex. This may lead to denial of service in applications that evaluate user-provided JSONata expressions.

### Patches This issue has been addressed in JSONata version 2.2.0 or later, and 1.8.9 or later on v1, via fixes that include https://github.com/jsonata-js/jsonata/pull/782 and https://github.com/jsonata-js/jsonata/pull/793. Applications that evaluate user-provided expressions should update ASAP to prevent exploitation.
