CVE-2026-120825

Improper Authorization in MongoDB Server Aggregation Framework View Definition Validation Leads to Unauthorized Collection Access

Published Nov 10, 2026 CVSS 4.0 · 7.1 High EPSS < 1% KEV · Not listed
Description
An authorization weakness in the aggregation framework of MongoDB Server may allow an authenticated user holding only basic database privileges to read the contents of collections in a database for which they have not been granted read access. The privilege evaluation performed while a view definition is validated does not cover a nested portion of the supplied pipeline, so the resulting view returns data the user is otherwise refused. This may result in unintended access to data, including stored authentication material.
