CVE-2026-76794: MongoDB BI Connector Transition Readiness Report Improper HTML Encoding When Processing Database Metadata
MongoSQL Transition Readiness Tool does not sufficiently encode database metadata before including it in generated HTML. A MongoDB user with write access can introduce crafted metadata that may cause script code to run when another user generates and opens the report, potentially exposing report contents or altering its display.
Event History
Frequently Asked Questions
Who is exposed to this issue?
Users who generate and open HTML reports with the MongoSQL Transition Readiness Tool are exposed if the processed database metadata can be modified by another MongoDB user. The attacker needs MongoDB write access to introduce crafted metadata.
What user interaction is required for exploitation?
A user must generate and open a report containing the crafted metadata. The injected script may then run in that user's report-viewing context.
What could an attacker do if exploitation succeeds?
The issue may expose the contents of the generated report or allow an attacker to alter how the report is displayed. Availability impact is not indicated.
