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