Description

This security bulletin contains information about 1 vulnerability.


1) Integer overflow (CVE-ID: CVE-2026-107324)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: 8.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to integer overflow in BSON value-length validation in MongoDB Go Driver when calculating binary element sizes. A remote attacker can supply a crafted BSON document containing a binary element with a declared length of math.MaxInt32 to cause a denial of service.

Exploitation requires an application to call bson.Raw.Validate on untrusted bytes, including bytes received from an untrusted server.
