{"id":"CVE-2026-49297","state":"PUBLISHED","title":"Apache Airflow Google provider: Path traversal via GCS object names → local/SFTP filesystem (GCSToSFTPOperator + GCSTimeSpanFileTransformOperator)","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.","publishedAt":"2026-07-06T09:54:07.148Z","updatedAt":"2026-07-06T19:26:04.051Z","severity":{"score":8.1,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","source":"CISA-ADP"},"assigner":"apache","products":["Apache Software Foundation Apache Airflow Google provider"],"affected":[{"vendor":"Apache Software Foundation","product":"Apache Airflow Google provider","packageName":"apache-airflow-providers-google","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"22.2.1","versionType":"semver"}],"collectionURL":"https://pypi.python.org"}],"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"],"weaknesses":["CWE-22"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/49xxx/CVE-2026-49297.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-49297","state":"PUBLISHED","datePublished":"2026-07-06T09:54:07.148Z","dateUpdated":"2026-07-06T19:26:04.051Z","assignerShortName":"apache","assignerOrgId":"f0158376-9dc2-43b6-827c-5f631a4d8d09","dateReserved":"2026-05-28T20:42:43.353Z"},"containers":{"cna":{"title":"Apache Airflow Google provider: Path traversal via GCS object names → local/SFTP filesystem (GCSToSFTPOperator + GCSTimeSpanFileTransformOperator)","descriptions":[{"lang":"en","value":"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.
