{"cve":"CVE-2026-86792","nvd":{"published":"2026-09-16T10:16:55.060","modified":"2026-09-18T14:30:06.090","status":"Analyzed","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-470"],"references":["https://github.com/apache/airflow/pull/72208","https://lists.apache.org/thread/jl4gpok02313yh3rvtvj8qbo11c6zpr2","https://lists.apache.org/thread/jl4gpok02313yh3rvtvj8qbo11c6zpr2?users@airflow.apache.org","http://www.openwall.com/lists/oss-security/2026/09/15/15"],"products":["apache:apache-airflow-providers-apache-kafka"],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-86792","score":0.01189,"percentile":0.6794,"date":"2026-10-31"},"kev":null,"osv":[{"id":"PYSEC-2026-3986","url":"https://osv.dev/vulnerability/PYSEC-2026-3986","summary":"","modified":"2026-09-19T23:00:02.763316321Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow-providers-apache-kafka","purl":"pkg:pypi/apache-airflow-providers-apache-kafka","ranges":[">=1.15.0 <2.0.0"],"fixed":["2.0.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
