Description
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.5.2-alpha.6 and 8.6.19, the validation for protected fields only checks top-level query keys. By wrapping a query constraint on a protected field inside a logical operator, the check is bypassed entirely. This allows any authenticated user to query on protected fields to extract field values. All Parse Server deployments have default protected fields and are vulnerable. This vulnerability is fixed in 9.5.2-alpha.6 and 8.6.19.
Analysis
Parse Server versions prior to 9.5.2-alpha.6 and 8.6.19 allow authenticated users to bypass field protection checks by nesting query constraints within logical operators, enabling unauthorized extraction of protected field values. This vulnerability affects all Parse Server deployments with default protected fields, as the validation mechanism only inspects top-level query keys. …
