NewCVE-2026-30972 (opens in a new tab)How to fix?
Upgrade parse-server to version 8.6.23, 9.5.2-alpha.10 or higher.
Overview
parse-server is a version of the Parse backend that can be deployed to any infrastructure that can run Node.js.
Affected versions of this package are vulnerable to Improper Control of Interaction Frequency in the batch endpoint, which processes sub-requests internally and bypasses the intended rate limiting controls. An attacker can send multiple sub-requests within a single batch to exceed the configured request limits by circumventing the middleware responsible for enforcing rate limits.
Note: This is only exploitable if the deployment relies solely on the built-in rate limiting feature without additional protections such as a reverse proxy or web application firewall.
