Description
CVE-2026-120816 is an authorization vulnerability in MongoDB Server where users with basic read-tier privileges can exploit a server-side data-change notification feature to access contents of certain restricted internal collections. The privilege check for this feature only considers the target namespace and ignores additional options that allow access to otherwise restricted data. This flaw affects multiple MongoDB Server versions prior to fixed releases.
