Improper Encoding of Server-Supplied JavaScript Values in MongoDB Compass BSON Parsing
CVE-2026-113870 is fixed in 3 products on 1 platform, first by MongoDB Compass 1.49.15.0, released August 25, 2026. It is not reported as exploited. Patch Radar priority: High.
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.
