Overview
Affected versions of this package are vulnerable to Incorrect Behavior Order through the apply_patch process. An attacker can cause unintended deletion of addressable members in the target document by supplying a specially crafted patch document that triggers a replace operation missing its value member or a move operation with an invalid destination path, resulting in data loss even when the API reports a failure.
