Overview

Affected versions of this package are vulnerable to Out-of-bounds Read in the parsing of BSONColumn data containing a CodeWScope element due to a missing bounds check in the accessors. An attacker can cause a server crash or disclose adjacent heap memory contents by submitting a crafted aggregation pipeline with malformed BSONColumn data that bypasses wire-level BSON validation.
