Parse Javascript SDK provides access to the powerful Parse Server backend from your JavaScript app. Prior to 7.0.0, injection of malicious payload allows attacker to remotely execute arbitrary code. ParseObject.fromJSON, ParseObject.pin, ParseObject.registerSubclass, ObjectStateMutations (internal), and encode/decode (internal) are affected. This vulnerability is fixed in 7.0.0.
