CVE-2026-120825
Improper Authorization in MongoDB Server Aggregation Framework View Definition Validation Leads to Unauthorized Collection Access
CVSS Score
6.5
EPSS Score
0.0%
EPSS Percentile
0th
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.
