CVE-2026-113870 · Severity: high · CVSS 8.8 · Published 2026-10-21

MongoDB Compass is a graphical tool used by database administrators to manage and query MongoDB databases. When a user opens a specially crafted stored view for editing, improperly escaped BSON values in the aggregation pipeline can trigger arbitrary code execution with the user's privileges. An attacker who can store a malicious view in a MongoDB deployment could compromise any administrator who opens that view.

## Technical details

The vulnerability exists in MongoDB Compass's conversion of a stored view's aggregation pipeline into editable source code, where certain BSON values are improperly escaped. This allows injection of malicious code that executes when a user opens the view for editing. The attack requires network access to a MongoDB deployment and for a user to interact with the malicious view, but does not require prior authentication to Compass itself.
