JSON

Jawn is an open source JSON parser. 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.
