CVE-2026-93760

HIGH 8.3 ALL-YEARS

Published 2026-09-18 · Last modified 2026-09-21 · mongodb · NVD: Analyzed

Mongoid does not restrict which query operators may come from caller-supplied filter data when an application hands that data to its query-building methods. In an application that forwards externally supplied filter parameters in this way, a party with no credentials may influence how the database evaluates the query. This may result in unintended disclosure of stored field values and in reduced database performance.
