Summary

The MongoDB Node.js Driver from 6.11.0 before 6.22.0 and from 7.0.0 before 7.8.0 is affected. A connection management flaw (CWE-226) can return a pooled connection for reuse while data from an earlier timed-out operation is still outstanding on it. In applications that enable the optional client-side operation timeout, an unauthenticated party who can send ordinary requests can cause database replies to be paired with the wrong requests. This can expose other users' records, return incorrect results and fail legitimate requests.

Description from the CNA

A flaw in the connection management layer of the MongoDB Node.js driver can leave a pooled network connection in the pool for reuse while data from an earlier operation is still outstanding on it. In applications that enable an optional client-side operation timeout, an unauthenticated party that can send ordinary requests to the application may cause database replies to be paired with the wrong requests. This may result in unintended disclosure of other users' records, incorrect operation results being returned, and failures of legitimate requests.
