CVE-2026-88031: Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB Go Driv

Routine

HIGH 8.1UPGRADE

CVE-2026-88031 is a high-severity flaw (CVSS 8.1) affecting go driver. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Improper neutralization of special elements in data query logic in the GridFS component of the MongoDB Go Driver can cause a caller-supplied structured file identifier to be interpreted as a query condition rather than as a literal identifier. An authenticated user who can influence the identifier passed by an affected application may cause all GridFS file chunks in the affected bucket to be removed, rendering stored file content unreadable.

Why this priority

High severity

A fixed release or distro patch exists.

mongodb go driver UPGRADE

Affected: >= 1.0.0 and < 1.17.10 · >= 2.0.0 and < 2.9.1

Fixed in: 1.17.10, 2.9.1

Safe to downgrade to: a release before 1.0.0

1. Check installed version

apt-cache policy go-driver || rpm -q go-driver || go-driver --version

2. UPGRADE to 1.17.10 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade go-driver

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade go-driver

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 1.0.0 (Debian / Ubuntu)

apt-cache madison go-driver sudo apt install go-driver=<VERSION_BEFORE_1.0.0> sudo apt-mark hold go-driver

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list go-driver sudo dnf downgrade go-driver-<VERSION_BEFORE_1.0.0> sudo dnf versionlock add go-driver

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
