Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0-alpha.21 and 8.6.45, 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. Starting in version 9.6.0-alpha.21 and 8.6.45, 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. No known workarounds are available.

Recommended fix High confidence

Parse Server 8.6.45 or 9.6.0

  1. Upgrade Parse Server to version 8.6.45 (if using major version 8.x) or 9.6.0 (if using major version 9.x)
  2. After upgrading, enable the `requestComplexity.queryDepth` server option in your server configuration
  3. Set `requestComplexity.queryDepth` to a value appropriate for your application (e.g., start with 10) to prevent deeply nested queries from crashing the server
  4. Restart the Parse Server to apply the configuration changes
Caveat The query depth limit is disabled by default to avoid breaking changes; you must explicitly enable and configure it after upgrading
