CVE-2026-116165: Parse Server Unauthenticated Class Schema Deletion Vulnerability

Short explanation

Parse Server versions contain a missing authorization vulnerability on MongoDB deployments. This allows clients without the master key to delete the stored schema of any class.

Why does it matter?

Unauthenticated attackers can send REST API delete requests targeting the internal _SCHEMA collection to remove field definitions and protected fields, exposing data to unauthorized reads and modifications.

What should be done?

  • Follow vendor advisories and security updates
  • Update affected versions or apply vendor recommendations
  • Review network-based access controls
