Extenders of the org.typelevel.jawn.SimpleFacade and org.typelevel.jawn.MutableFacade who don't override objectContext() are vulnerable to a hash collision attack. Most applications do not implement these traits directly, but inherit from a library:
Affected implementations include:
org.http4s :: http4s-play-jsonorg.typelevel :: jawn-ast (< 0.8.0)org.typelevel :: jawn-play (discontinued)org.typelevel :: jawn-rojoma (discontinued)org.typelevel :: jawn-spray (discontinued)Unaffected implementations include:
io.argonaut :: argonaut-jawnio.circe :: circe-parserorg.typelevel :: jawn-ast (>= 0.8.0)org.typelevel :: jawn-json4s (discontinued)org.typelevel :: jawn-argonaut (discontinued)jawn-parser-1.3.2 fixes the issue.
Override objectContext() to use a collision-safe collection. See the patch for an example in both SimpleFacade and MutableFacade.
