CVE-2021-41109

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to version

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to version 4.10.4, for regular (non-LiveQuery) queries, the session token is removed from the response, but for LiveQuery payloads it is currently not. If a user has a LiveQuery subscription on the Parse.User class, all session tokens created during user sign-ups will be broadcast as part of the LiveQuery payload.

A patch in version 4.10.4 removes session tokens from the LiveQuery payload. As a workaround, set user.acl(new Parse.ACL()) in a beforeSave trigger to make the user private already on sign-up.
