Description

A command for refining a collection shard key is missing an authorization check. This may cause the command to run directly on a shard, leading to either degradation of query performance, or to revealing chunk boundaries through timing side channels. This affects MongoDB Server v5.0 versions, prior to 5.0.22, MongoDB Server v6.0 versions, prior to 6.0.11 and MongoDB Server v7.0 versions prior to 7.0.3.

Affected products

• MongoDB: from 5.0.0 before 5.0.22; from 6.0.0 before 6.0.11; from 7.0.0 before 7.0.3 — fixed in 5.0.22, 6.0.11, 7.0.3

How to fix

Upgrade to a fixed version: MongoDB 5.0.22, 6.0.11, 7.0.3. Check the vendor advisory for mitigations.
