How to fix?

There is no fixed version for Echo:latest pymongo.

NVD Description

Note: Versions mentioned in the description apply only to the upstream pymongo package and not the pymongo package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

PyMongo's connection string parsing decodes percent-encoded characters in the host portion before the host list is separated on its delimiters. When an application places a hostname value supplied by an unauthenticated party into a connection string, that party may cause additional servers of their choosing to be added to the application's database client. The application may then send its authentication exchange and database operations to one of those servers, which can observe limited information and return altered results.
