{"id":"CVE-2026-86792","published":"2026-09-16T10:16:55.060","lastModified":"2026-09-18T14:30:06.090","description":"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 process, so a user whose only privilege is editing Airflow connections gains arbitrary code execution in the control plane; the Airflow security model limits connection-configuration users to code execution on workers, not the scheduler. Deployments using Google Managed Kafka are not affected, because that code path overwrites any user-supplied `oauth_cb`; plain brokers and Amazon MSK are exposed. Users are recommended to upgrade to apache-airflow-providers-apache-kafka 2.0.0 or later, which adds an allowlist configuration option for connection-string callbacks.","cvssScore":8.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-470"],"vendors":["apache"],"products":["apache-airflow-providers-apache-kafka"],"references":[{"url":"https://github.com/apache/airflow/pull/72208","tags":["Patch","Vendor Advisory"]},{"url":"https://lists.apache.org/thread/jl4gpok02313yh3rvtvj8qbo11c6zpr2","tags":["Mailing List","Vendor Advisory"]},{"url":"https://lists.apache.org/thread/jl4gpok02313yh3rvtvj8qbo11c6zpr2?users@airflow.apache.org","tags":["Mailing List","Vendor Advisory"]},{"url":"http://www.openwall.com/lists/oss-security/2026/09/15/15","tags":["Mailing List","Vendor Advisory"]}],"exploitRefs":[{"url":"https://github.com/apache/airflow/pull/72208","tags":["Patch","Vendor Advisory"]}],"hasPoc":true,"ai":{"summary":"The flaw allows a user with permission to edit Airflow connections to execute arbitrary code in the scheduler process, which is outside the typical scope of their privileges.","exploitability":"Exploitation requires access to edit Airflow connections and has a moderate level of difficulty due to the need to craft a specific `extra` field payload.","blast_radius":"If exploited, the impact is high, as it could lead to full control of the Airflow scheduler process, potentially affecting the entire system.","remediation":"Upgrade to apache-airflow-providers-apache-kafka 2.0.0 or later, which introduces an allowlist configuration option for connection-string callbacks.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["rce","airflow","kafka","python","code-execution"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-09-30T09:17:10.690Z"}}
