Extenders of the `org.typelevel.jawn.SimpleFacade` and `org.typelevel.jawn.MutableFacade` who don't override `objectContext()` are vulnerable to a hash collision attack which may result in a denial of service. Most applications do not implement these traits directly, but inherit from a library. `jawn-parser-1.3.1` fixes this issue and users are advised to upgrade. For users unable to upgrade override `objectContext()` to use a collision-safe collection.\n\ud83d\udccf Published: 2022-01-05T21:00:12.000Z\n\ud83d\udccf Modified: 2025-04-22T18:34:05.348Z\n\ud83d\udd17 References:\n1. https://github.com/typelevel/jawn/security/advisories/GHSA-vc89-hccf-rq55\n2. https://github.com/typelevel/jawn/pull/390", "creation_timestamp": "2025-04-22T19:03:45.000000Z"}
