Title

Improper Authorization in MongoDB Atlas Vector Search Allows Unauthorized Access to Protected View Data

Summary

An issue in MongoDB Server's Atlas Vector Search feature could allow an authenticated user with read access to one view to retrieve documents from a different, protected view over the same underlying collection. This is due to insufficient handling of certain user-supplied fields when constructing an internal request forwarded to the search process.
