CVE-2022-21653
Good to know:
Date: January 5, 2022
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.
