GHSA-9f2h-7v79-mxw3: Parse Javascript SDK vulnerable to prototype pollution in `Parse.Object` and internal APIs
Summary
Prototype pollution capabilities on various APIs.
Details
Injection of malicious payload allows attacker to remotely execute arbitrary code. Parse.Object and internal APIs are affected, specifically:
ParseObject.fromJSONParseObject.pinParseObject.registerSubclassObjectStateMutations(internal)encode/decode(internal)
PoC
Demonstrative tests added as part of the fix.

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
