CVE-2026-114647 · NoSQL operator injection via unvalidated replacement document in findOneAndReplace
This page contains facts from public vulnerability sources. Check the original advisory before updating.
The MongoDB C# Driver does not reject replacement documents whose top-level field names begin with a dollar sign in FindOneAndReplace, unlike other replace operations. An application that builds such a document from user-supplied field names can have the server apply update operators instead of a full replacement. The effect is limited to the document matched by the application's own filter, whose contents can be modified in ways the application did not intend.
