What is CVE-2025-64502?

Parse Server, an open source backend for Node.js, has a critical vulnerability that allows any client to execute the MongoDB explain() method without requiring the master key. This exposure can reveal sensitive information about database schema structures, index usage, performance metrics, and potential attack vectors. Version 8.5.0-alpha.5 introduces a new databaseOptions.allowPublicExplain setting to restrict access to explain queries, which defaults to true to maintain compatibility with existing systems. Users are advised to implement middleware to block these queries from non-master-key requests or to monitor their usage for enhanced security.
