This month

HIGH 7.5WATCHLISTUPGRADE

CVE-2026-14265 is a high-severity flaw (CVSS 7.5) affecting advanced jdbc wrapper. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Deserialization of untrusted data in the RemoteQueryCachePlugin in Amazon Web Services AWS Advanced JDBC Wrapper 3.3.0 through 4.0.0 might allow an actor with write access to the shared cache infrastructure to execute arbitrary code on application servers that read cached query results via a crafted serialized Java object. The RemoteQueryCachePlugin uses ObjectInputStream without class filtering when deserializing cached query results from Redis

amazon advanced jdbc wrapper UPGRADE

Affected: >= 3.3.0 and < 4.0.1

Fixed in: 4.0.1

Safe to downgrade to: a release before 3.3.0

1. Check installed version

apt-cache policy advanced-jdbc-wrapper || rpm -q advanced-jdbc-wrapper || advanced-jdbc-wrapper --version

2. UPGRADE to 4.0.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade advanced-jdbc-wrapper

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade advanced-jdbc-wrapper

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 advanced-jdbc-wrapper sudo apt install advanced-jdbc-wrapper=<VERSION_BEFORE_3.3.0> sudo apt-mark hold advanced-jdbc-wrapper

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

dnf --showduplicates list advanced-jdbc-wrapper sudo dnf downgrade advanced-jdbc-wrapper-<VERSION_BEFORE_3.3.0> sudo dnf versionlock add advanced-jdbc-wrapper

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.
