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

Type: advisorySource: OSV1 source record

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.
