## Overview

### Impact

An unauthenticated attacker can crash the Parse Server process by sending a single request with deeply nested query condition operators. This terminates the server and denies service to all connected clients.

### Patches

A depth limit for query condition operator nesting has been added via the `requestComplexity.queryDepth` server option. The option is disabled by default to avoid a breaking change. To mitigate, upgrade and set the option to a value appropriate for your app.

### Workarounds

None.

## Affected packages

- `parse-server >= 9.0.0, < 9.6.0-alpha.21`
- `parse-server < 8.6.45`

## Remediation

Upgrade to a patched release:

- `parse-server 9.6.0-alpha.21`
- `parse-server 8.6.45`
