    Summary: Improper Validation in MongoDB Server Aggregation Framework Allows Authorization Bypass and Unauthorized Collection Access with Atlas Search

    Details: A security issue in the MongoDB Server aggregation framework allows an authenticated user with limited read privileges to bypass view-level authorization checks and access data from unauthorized collections when Atlas Search features are in use. The issue stems from insufficient validation of an internal command parameter that can be set by external clients, causing a security check to be improperly skipped.
