Parse Server crash via deeply nested query condition operators
Details
### 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.
