Summary

MongoDB Compass from 1.7.0 before 1.49.15 improperly escapes certain BSON values (CWE-116) when it converts a stored view's aggregation pipeline into editable source. When a user connects to a deployment containing a specially crafted view and opens that view for editing, the values can cause arbitrary code to execute with the privileges of the user running Compass.
