CVE-2026-30962 Details
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.
A vulnerability in Parse Server prior to versions 9.5.2-alpha.6 and 8.6.19 allows authenticated users to bypass validation on protected fields. The issue arises because the validation only considers top-level query keys. By enclosing a query constraint for a protected field within a logical operator, the validation is completely circumvented. This flaw enables extraction of field values from protected areas. All default Parse Server deployments are affected.
Users can update to Parse Server versions 9.5.2-alpha.6 or 8.6.19 to address this vulnerability. Alternatively, a 'beforeFind' trigger can be used on affected classes to manually check queries for references to protected fields in logical operator sub-queries and reject those requests.
