Routine

MEDIUM 6.5UPGRADE

CVE-2026-18710 is a medium-severity flaw (CVSS 6.5) affecting java driver. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A MongoDB driver component could write sensitive configuration information, including a credential used for outbound network connectivity, to application log output in cleartext during routine client initialization. This occurs automatically as part of normal operation and requires no special privileges to trigger. A party able to read the affected application's logs or downstream log-aggregation storage could recover the credential and reuse it

Why this priority

No elevated risk signals yet

A fixed release or distro patch exists.

mongodb java driver UPGRADE

Affected: >= 4.11.1 and < 5.9.2

Fixed in: 5.9.2

Safe to downgrade to: a release before 4.11.1

1. Check installed version

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

2. UPGRADE to 5.9.2 (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 4.11.1 (Debian / Ubuntu)

apt-cache madison java-driver sudo apt install java-driver=<VERSION_BEFORE_4.11.1> 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_4.11.1> 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.
