CVE-2026-88033 is a high-severity flaw (CVSS 8.3) affecting java 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 Java 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 obtain stored file content beyond the intended target or cause all GridFS file chunks in the affected bucket to

mongodb java driver UPGRADE

Affected: >= 3.3.0 and < 5.11.1

Fixed in: 5.11.1

Safe to downgrade to: a release before 3.3.0

1. Check installed version

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

2. UPGRADE to 5.11.1 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade java-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 3.3.0 (Debian / Ubuntu)

apt-cache madison java-driver sudo apt install java-driver=<VERSION_BEFORE_3.3.0> sudo apt-mark hold java-driver

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

dnf --showduplicates list java-driver sudo dnf downgrade java-driver-<VERSION_BEFORE_3.3.0> sudo dnf versionlock add java-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.
