CVE-2026-24012 is a high-severity flaw (CVSS 7.5) affecting iotdb. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Uncontrolled Resource Consumption vulnerability in Apache IoTDB. Some interface fails to impose reasonable limits on the time span and aggregation interval of the query. An attacker can construct a request with extreme parameters (e.g., a very large time range combined with a minimal interval). This forces the DataNode to build an enormous result set in memory, which exhausts the Java heap and causes the DataNode process to crash. This issue a

apache iotdb UPGRADE

Affected: >= 1.3.3 and < 2.0.8

Fixed in: 2.0.8

Safe to downgrade to: a release before 1.3.3

1. Check installed version

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

2. UPGRADE to 2.0.8 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade iotdb

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 1.3.3 (Debian / Ubuntu)

apt-cache madison iotdb sudo apt install iotdb=<VERSION_BEFORE_1.3.3> sudo apt-mark hold iotdb

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

dnf --showduplicates list iotdb sudo dnf downgrade iotdb-<VERSION_BEFORE_1.3.3> sudo dnf versionlock add iotdb

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.
