Short explanation

A vulnerability exists in Mongoose where countDocuments() fails to apply the configured sanitizeFilter defense. This can cause query operators to be processed incorrectly and undermine authorization logic.

Why does it matter?

Attackers can bypass controls when sanitizeFilter is enabled and compromise sensitive application logic.

What should be done?

  • Follow vendor advisory guidelines
  • Update Mongoose versions

Show the technical text from the sources

Mongoose is a MongoDB object modeling tool designed to work in an asynchronous environment. Prior to 6.13.11, 7.8.12, 8.24.3, and 9.9.2, Mongoose countDocuments() does not apply the configured sanitizeFilter query selector injection defense. An application that enables sanitizeFilter and passes attacker-controlled filter values to countDocuments() can therefore process query operator objects as operators rather than literal values, causing the count to include documents that should not match and potentially undermining authorization or application logic based on that count. This issue is fixed in versions 6.13.11, 7.8.12, 8.24.3, and 9.9.2.
