CVE-2026-32098 Details
Description
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 9.6.0-alpha.9 and 8.6.35, an attacker can exploit LiveQuery subscriptions to infer the values of protected fields without directly receiving them. By subscribing with a WHERE clause that references a protected field (including via dot-notation or $regex), the attacker can observe whether LiveQuery events are delivered for matching objects. This creates a boolean oracle that leaks protected field values. The attack affects any class that has both protectedFields configured in Class-Level Permissions and LiveQuery enabled. This vulnerability is fixed in 9.6.0-alpha.9 and 8.6.35.
A vulnerability in Parse Server's LiveQuery feature allows attackers to infer values of protected fields without direct access. This issue exists in versions 9.0.0 prior to 9.6.0-alpha.9 and in versions prior to 8.6.35. The vulnerability arises when LiveQuery subscriptions include a WHERE clause referencing protected fields, either directly or through dot notation or regular expressions. This creates a boolean oracle, leaking protected data from any class with LiveQuery enabled and protected fields configured in Class-Level Permissions.
Users can upgrade to Parse Server versions 9.6.0-alpha.9 or 8.6.35, where this vulnerability has been patched. Alternatively, LiveQuery can be disabled for classes using protected fields, or protected fields can be removed from classes that require LiveQuery.
