Description

This security bulletin contains information about 1 vulnerability.


1) Improper Validation of Array Index (CVE-ID: CVE-2026-107325)

CWE-ID: CWE-129 - Improper Validation of Array Index

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 improper validation of array lengths used to calculate array indices in bson.RawArray.Validate when validating untrusted BSON arrays. A remote attacker can supply a crafted BSON array with a declared length of zero to cause a denial of service.

A four-byte payload consisting entirely of zero bytes triggers an index-out-of-range runtime panic.
