Parse Server: Query condition depth bypass via pre-validation transform pipeline
CVE-2026-33498
Description
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.55 and 9.6.0-alpha.44, an attacker can send an unauthenticated HTTP request with a deeply nested query containing logical operators to permanently hang the Parse Server process. The server becomes completely unresponsive and must be manually restarted. This is a bypass of the fix for CVE-2026-32944. This issue has been patched in versions 8.6.55 and 9.6.0-alpha.44.
