Improper Authorization in MongoDB applyOps Command Handling Allows Unauthorized DDL Operations on Collections
An issue in MongoDB Server's applyOps command could allow an authenticated user with specific non-default privileges to perform certain data-definition operations, such as dropping or modifying collections, against collections they do not have permission to manipulate. This is due to an inconsistency in how the target collection is determined between the authorization check and the actual operation.
