Vulnerability from github – Published: 2021-09-30 17:09 – Updated: 2021-09-30 16:43

Summary

LiveQuery publishes user session tokens in parse-server

Details

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.

Severity

7.5 (High)

CVE-2021-41109 (GCVE-0-2021-41109)

Vulnerability from cvelistv5 – Published: 2021-09-30 15:10 – Updated: 2024-08-04 02:59

Title

LiveQuery publishes user session tokens

Summary

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.

Severity

7.5 (High)
