CVE-2026-107325

Application denial of service via missing BSON array length validation in MongoDB Go Driver

Published Oct 8, 2026 CVSS 4.0 · 8.2 High EPSS < 1% KEV · Not listed
Description
Improper validation of a BSON array length in the MongoDB Go Driver can cause an out-of-bounds index and runtime panic when an application calls bson.RawArray.Validate or bsoncore.Array.Validate on a malformed four-byte array. An unauthenticated actor who can supply raw BSON array data to an affected application may terminate an unprotected application process, causing a denial of service. No confidentiality or integrity impact has been identified.
