CVE-2025-59355 is a medium-severity flaw (CVSS 6.5) affecting linkis. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A vulnerability. When org.apache.linkis.metadata.util.HiveUtils.decode() fails to perform Base64 decoding, it records the complete input parameter string in the log via logger.error(str + "decode failed", e). If the input parameter contains sensitive information such as Hive Metastore keys, plaintext passwords will be left in the log files when decoding fails, resulting in information leakage. Affected Scope Component: Sensitive fields in hive

apache linkis UPGRADE

Affected: >= 1.0.0 and < 1.8.0

Fixed in: 1.8.0

Safe to downgrade to: a release before 1.0.0

1. Check installed version

apt-cache policy linkis || rpm -q linkis || linkis --version

2. UPGRADE to 1.8.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade linkis

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade linkis

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 linkis sudo apt install linkis=<VERSION_BEFORE_1.0.0> sudo apt-mark hold linkis

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

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

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.
