CVE-2026-34573

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.68 and 9.7.0-alpha.12, the GraphQL query complexity validator can be exploited to cause a denial-of-service by sending a crafted query with binary fan-out fragment spreads...

CVE-2026-32944

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.21 and 8.6.45, an unauthenticated attacker can crash the Parse Server process by sending a single request with deeply nested query condition operators. This terminates the...

Uncontrolled Recursion

Overview parse-server is a version of the Parse backend that can be deployed to any infrastructure that can run Node.js. Affected versions of this package are vulnerable to Uncontrolled Recursion via the requestComplexity.queryDepth configuration setting when processing WebSocket subscription...
