NewCVE-2026-100631 (opens in a new tab)How to fix?
Upgrade parse-server to version 8.6.90, 9.10.1-alpha.9 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 Neutralization of Special Elements in Data Query Logic via operator injection in the handleInstallation function in src/RestWrite.js, where client-supplied fields deviceToken, installationId, and appIdentifier are embedded directly into privileged database queries used for device token deduplication without type enforcement. An unauthenticated attacker can supply a query operator object (such as {"$ne": null}) in place of a string value, causing the deduplication logic to match and delete installation records far beyond those the client identified, resulting in mass unauthenticated deletion of push notification installation records.
