Unauthenticated query-plan disclosure via unchecked explain requests
Published Nov 10, 2025 · Updated Nov 10, 2025
Information disclosure in Parse Server before 8.5.0-alpha.5 allows remote attackers to read MongoDB query-plan details via explain queries. REST query handling forwards the client-controlled explain parameter to MongoDB without requiring the master key, returning schema fields, indexes, execution statistics, and optimization details. Any network client with the application's public application ID can reach the behavior; the disclosure does not modify data or interrupt service.
