Description
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.fromJSON
- ParseObject.pin
- ParseObject.registerSubclass
- ObjectStateMutations (internal)
- encode/decode (internal)
PoC
Demonstrative tests added as part of the fix.

Click to expand
- Attack vector (AV:N)
- Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
- Attack complexity (AC:L)
- Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
- Privileges required (PR:L)
- A normal user session is enough; they don’t have to be admin.
- User interaction (UI:N)
- Nobody has to click “OK” or open a trap file; it can work without a victim helping.
- Scope (S:C)
- Breaking this can reach past the original component and bite other resources—bigger blast radius.
- Confidentiality (C:L)
- Some sensitive info could get out, but not a total data dump.
- Integrity (I:N)
- Data isn’t meaningfully altered or forged.
- Availability (A:L)
- Might cause slowdowns, glitches, or partial disruption—not a full brick.
