CVE-2026-125119 · Severity: high · CVSS 7.5 · Published 2026-11-09

Mongoose is an object-data mapper for MongoDB that prevents query injection attacks through a sanitizeFilter option. When this option is enabled at the connection level, it fails to activate during queries, leaving applications vulnerable to attackers injecting MongoDB operators into filter values to bypass authentication or retrieve unauthorized data.

Technologies: [Automattic Mongoose](https://junglewise.ai/threats/technologies/automattic-mongoose), [mongoose (npm)](https://junglewise.ai/threats/technologies/mongoose). Vendors: [Automattic](https://junglewise.ai/threats/vendors/automattic), [npm](https://junglewise.ai/threats/vendors/npm).

## How to fix

- mongoose (npm): upgrade to 6.13.12 or later

  ```sh
  npm install mongoose@6.13.12
  ```


## Technical details

The sanitizeFilter option, introduced in Mongoose 6.0.0, is stored in Connection.config but Query#_castConditions() only checks Connection.options, causing the defense to be skipped despite Connection#get('sanitizeFilter') returning true. An attacker controlling filter input can inject operators like {$ne: null} to manipulate query logic, such as bypassing password checks via {password: {$ne: null}}. The vulnerability affects connection-level configuration but not global or per-query settings.

## Affected products

- Automattic Mongoose 6.0.0 through 9.11.2
