NewCVE-2026-125120 (opens in a new tab)How to fix?
Upgrade mongoose to version 6.13.11, 7.8.12, 8.24.3, 9.9.2 or higher.
Overview
mongoose is a Mongoose is a MongoDB object modeling tool designed to work in an asynchronous environment.
Affected versions of this package are vulnerable to Improper Neutralization of Special Elements in Data Query Logic via countDocuments() queries, which do not apply sanitizeFilter - Mongoose's mechanism for protecting against query selector injection attacks. An attacker who can control filter input to countDocuments() can inject MongoDB query selectors, bypassing the sanitization that is applied to other query methods. The fix extends _castConditions() (which internally invokes sanitizeFilter) to _countDocuments and cursor operations.
