NewCVE-2025-64502 (opens in a new tab)How to fix?
Upgrade parse-server to version 8.5.0-alpha.5 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 Insertion of Sensitive Information Into Sent Data via the Parse.Query.explain function which provides detailed information about query execution plans. An attacker can obtain sensitive database schema details and performance metrics by issuing public requests to this process without authentication.
Workaround
This vulnerability can be mitigated by implementing middleware to block explain queries from non-master-key requests, or by monitoring and alerting on explain query usage in production environments.
