Description Doran Moppert 2019-05-22 01:46:42 UTC

A possible vulnerability exists where type confusion can occur when manipulating JavaScript objects in object groups, allowing for the bypassing of security checks within these groups. 

*Note: this vulnerability has only been demonstrated with `UnboxedObjects`, which are disabled by default on all supported releases.*
