Mongoid Unrestricted Query Operator Use Allows Data Exploitation
CVE-2026-93760 Published on September 18, 2026

NoSQL injection of JavaScript-executing query operators via unsafe-by-default operator guard
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.
