Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Developers can use the REST API to signup users and also allow users to login anonymously. Prior to version 4.5.1, when an anonymous user is first signed up using REST, the server creates session incorrectly. Particularly, the authProvider
field in _Session
class under createdWith
shows the user logged in creating a password. If a developer later depends on the createdWith
field to provide a different level of access between a password user and anonymous user, the server incorrectly classified the session type as being created with a password
. The server does not currently use createdWith
to make decisions about internal functions, so if a developer is not using createdWith
directly, they are not affected. The vulnerability only affects users who depend on createdWith
by using it directly. The issue is patched in Parse Server version 4.5.1. As a workaround, do not use the createdWith
Session field to make decisions if one allows anonymous login.
