CVE-2026-93760: NoSQL injection of JavaScript-executing query operators via unsafe-by-default operator guard
- Severity: high (CVSS 8.2 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.5% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2026-09-18 · updated 2026-09-24
- Weakness: CWE-943
Description
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.
Affected products
- MongoDB Inc. Mongoid: from 8.0.0 before 8.0.13; from 8.1.0 before 8.1.13; from 9.0.0 before 9.0.12; 9.1.0 — fixed in 8.0.13, 8.1.13, 9.0.12
How to fix
Upgrade to a fixed version: MongoDB Inc. Mongoid 8.0.13, 8.1.13, 9.0.12. Check the vendor advisory for mitigations.
