MongoDB Compass: improper output encoding
Fix: upgrade to 1.49.15 or later
MongoDB Compass improperly escapes certain BSON values when converting a stored view’s aggregation pipeline into editable source. When a user connects to a MongoDB 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.
Affected versions
| Package | Affected | Fixed in |
|---|---|---|
| Compass Product | >= 1.7.0, < 1.49.15 | 1.49.15 |
