CVE-2026-107324Application denial of service via integer overflow in BSON value-length validation in MongoDB Go Driver

Updated under an hour ago ()

Does this affect you?

It affects MongoDB Go Driver. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

An integer overflow in BSON value-length handling in the MongoDB Go Driver can cause a runtime panic when an application validates or accesses a malformed BSON document. An unauthenticated actor who can supply BSON bytes to an affected application may terminate an unprotected application process, causing a denial of service. The driver's server-monitoring path contains panic recovery and is limited to server-selection failure.
