CVE-2026-93760: 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.

Frequently Asked Questions
Which applications are exposed?
Applications are exposed when they pass externally supplied filter parameters to Mongoid query-building methods without restricting the operators those parameters may contain. Mongoid itself does not restrict which query operators can originate from caller-supplied filter data.
Does exploitation require authentication or user interaction?
No. The supplied vector indicates network exploitation with low attack complexity, no privileges, and no user interaction; the description states that an unauthenticated party may influence query evaluation when the application forwards external filter data.
What is the likely impact of successful exploitation?
An attacker may cause the database to evaluate unintended query operators, potentially disclosing stored field values. The issue may also reduce database performance.
