Parse Server's custom object ID allows to acquire role privileges

  • Disclosed: 04.10.2024
  • Updated: 11.10.2026 10:22

Impact

If the Parse Server option allowCustomObjectId: true is set, an attacker that is allowed to create a new user can set a custom object ID for that new user that exploits the vulnerability and acquires privileges of a specific role.

Patches

Improved validation for custom user object IDs. Session tokens for existing users with an object ID that exploits the vulnerability are now rejected.

Workarounds

  • Disable custom object IDs by setting allowCustomObjectId: false or not setting the option which defaults to false.
  • Use a Cloud Code Trigger to validate that a new user's object ID doesn't start with the prefix role:.
