6.9 (Medium) CVSS_V4 - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N CVSS Calculator

Summary

ApostropheCMS: The general public can access @apostrophecms/user objects via a relationship (viewRole is not applied to the general public)

Details

Impact

Even though it is correctly applied to guests, contributors, etc., viewRole is not applied to the general public. This means that a secured content type like @apostrophecms/user can in theory be accessed.

This is greatly mitigated by the fact that there is no automatic public REST API for any content type. One has to expressly allow it. However, it does mean that developers can make the mistake of setting up a relationship between a content type like a blog post, and @apostrophecms/user. This could potentially expose some sensitive information if templates were written poorly, e.g. if they JSON-serialized the entire object. Note that password hashes are NOT affected because they reside in a separate collection.

The public demo project and its various flavors must be updated first because it inadvertently relies on the bug.

Patches

4.33.0

Workarounds

Never create relationships with @apostrophecms/user that are intended for non-admin display. If you need a relationship that expresses authorship, create a separate author piece type to publicly represent that.
