  "details": "Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior o 9.5.2-alpha.10 and 8.6.23, Parse Server's rate limiting middleware is applied at the Express middleware layer, but the batch request endpoint (/batch) processes sub-requests internally by routing them directly through the Promise router, bypassing Express middleware including rate limiting. An attacker can bundle multiple requests targeting a rate-limited endpoint into a single batch request to circumvent the configured rate limit. Any Parse Server deployment that relies on the built-in rate limiting feature is affected. This vulnerability is fixed in 9.5.2-alpha.10 and 8.6.23.",
