MongoSQL Transition Readiness Tool Improper Output Encoding in Generated HTML Reports

Published Aug 28, 2026 · Updated Aug 31, 2026 · Assigned by mongodb

Description

The MongoSQL Transition Readiness Tool writes query text and user names read from BI Connector log files into its generated HTML report without encoding them for that output context. A user able to issue queries through the BI Connector can influence log content so that markup supplied in a query is interpreted by the browser when an operator later generates and opens the report, which may disclose other users' logged query text and user names to an external party or present misleading content to the operator. Generating a report over logs containing the affected entries and opening that report in a browser is required.
