Affected packages
• npm parse-server: < 4.10.4 → fixed in 4.10.4
Description
Impact
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.
Patches
Remove session token from LiveQuery payload.
Workaround
Set `user.acl(new Parse.ACL())` in a beforeSave trigger to make the user private already on sign-up.
