# Parse Server: crafted object update crashes the Node process

Parse Server, a Node.js backend framework, fails to contain a serialization error when an object update uses a dot-notation key on a pointer field in a class that has an afterSave trigger. An attacker can send that update to crash the Node process, causing denial of service.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed version with `npm ls parse-server` in the project.
- Look for a class with an `afterSave` trigger whose objects accept writes from clients without a session.

## Fix

- Parse Server `8.6.110` or later in the 8.x line.
- Parse Server `9.10.6-alpha.2` or later in the 9.x line.

## From the sources

Parse Server before 8.6.110 and 9.0.0 before 9.10.6-alpha.2 fails to contain a serialization error when an object update uses a dot notation key targeting a pointer field's object identifier on a class with an afterSave trigger. Attackers, including unauthenticated clients when objects are writable without a session, can send such an update to crash the Node process.
