CVE-2026-86792: Apache Airflow Apache Kafka provider versions 1.15.0 before 2.0.0 resolve dotted-path strings found in a Kafka

This month

HIGH 8.8WATCHLISTUPGRADE

CVE-2026-86792 is a high-severity flaw (CVSS 8.8) affecting apache-airflow-providers-apache-kafka. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Apache Airflow Apache Kafka provider versions 1.15.0 before 2.0.0 resolve dotted-path strings found in a Kafka connection's `extra` field into Python callables via `import_string`, with no allowlist, and hand them to the confluent-kafka client which invokes them. Deployments that have enabled the Kafka event producer — `dag_run_events_enabled` or `task_instance_events_enabled`, both disabled by default — build that client inside the scheduler pro

apache apache-airflow-providers-apache-kafka UPGRADE

Affected: >= 1.15.0 and < 2.0.0

Fixed in: 2.0.0

Safe to downgrade to: a release before 1.15.0

1. Check installed version

apt-cache policy apache-airflow-providers-apache-kafka || rpm -q apache-airflow-providers-apache-kafka || apache-airflow-providers-apache-kafka --version

2. UPGRADE to 2.0.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade apache-airflow-providers-apache-kafka

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade apache-airflow-providers-apache-kafka

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 1.15.0 (Debian / Ubuntu)

apt-cache madison apache-airflow-providers-apache-kafka sudo apt install apache-airflow-providers-apache-kafka=<VERSION_BEFORE_1.15.0> sudo apt-mark hold apache-airflow-providers-apache-kafka

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

dnf --showduplicates list apache-airflow-providers-apache-kafka sudo dnf downgrade apache-airflow-providers-apache-kafka-<VERSION_BEFORE_1.15.0> sudo dnf versionlock add apache-airflow-providers-apache-kafka

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.
