{"cve":"CVE-2026-49297","nvd":{"published":"2026-07-06T11:16:30.207","modified":"2026-10-25T15:10:00.147","status":"Analyzed","description":"Apache Airflow's Google provider operators `GCSToSFTPOperator` and `GCSTimeSpanFileTransformOperator` joined GCS object names returned by the bucket listing API directly to a destination filesystem path without normalisation or containment check. A user with write access to the source GCS bucket (typically a different trust principal than the DAG author — partner uploads, ingest-only service accounts, public-data buckets) could create an object whose name contains `..` segments and cause the DAG run to write the downloaded blob outside the configured destination (the SFTP `destination_path` for `GCSToSFTPOperator`; the worker-local temp directory for `GCSTimeSpanFileTransformOperator`), enabling overwrite of arbitrary files on the SFTP server or the worker host. Affects deployments that ingest from buckets writable by less-trusted principals. Users are advised to upgrade to `apache-airflow-providers-google` 22.2.1 or later.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","score":8.1},"cwes":["CWE-22"],"references":["https://github.com/apache/airflow/pull/67667","https://lists.apache.org/thread/cb5nvoxsj1q7rv878cyqgtg150w0zglq?users@airflow.apache.org","http://www.openwall.com/lists/oss-security/2026/07/04/8"],"products":["apache:apache-airflow-providers-google"],"source":"nvd","synced_at":"2026-10-25T17:50:06.907763985+00:00"},"epss":{"cve":"CVE-2026-49297","score":0.00994,"percentile":0.62377,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-v3mh-27qj-w836","url":"https://osv.dev/vulnerability/GHSA-v3mh-27qj-w836","summary":"Apache Airflow Google provider allows path traversal through GCS object names","modified":"2026-09-04T19:40:33.043155846Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow-providers-google","purl":"pkg:pypi/apache-airflow-providers-google","ranges":["<22.2.1"],"fixed":["22.2.1"]}]},{"id":"PYSEC-2026-2084","url":"https://osv.dev/vulnerability/PYSEC-2026-2084","summary":"","modified":"2026-09-10T11:15:08.155028031Z","packages":[{"ecosystem":"PyPI","name":"apache-airflow-providers-google","purl":"pkg:pypi/apache-airflow-providers-google","ranges":["<22.2.1"],"fixed":["22.2.1"]}]}],"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).
