{"id":"CVE-2026-49818","state":"PUBLISHED","title":"Apache Airflow Samba provider: Path traversal in GCSToSambaOperator via GCS object names","description":"The Apache Airflow Samba provider's `GCSToSambaOperator` joined GCS object names to the SMB destination path without a containment check, so an object named with `../` segments resolved a write path outside the configured `destination_path`. An attacker able to write objects into the source GCS bucket — typically an external data producer distinct from the trusted DAG author — could write files to arbitrary locations on the Samba target when the operator ran. Upgrade apache-airflow-providers-samba to 4.12.6 or later, which validates the resolved destination stays within `destination_path`.","publishedAt":"2026-06-09T07:42:48.028Z","updatedAt":"2026-06-10T17:37:57.296Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","source":"CISA-ADP"},"assigner":"apache","products":["Apache Software Foundation Apache Airflow Samba provider"],"affected":[{"vendor":"Apache Software Foundation","product":"Apache Airflow Samba provider","packageName":"apache-airflow-providers-samba","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThan":"4.12.6","versionType":"semver"}],"collectionURL":"https://pypi.python.org"}],"references":["https://github.com/apache/airflow/pull/67857","https://lists.apache.org/thread/3vs0m3p51psgf54tts18d6336g24x3sf","http://www.openwall.com/lists/oss-security/2026/06/09/8"],"weaknesses":["CWE-22"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/49xxx/CVE-2026-49818.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-49818","state":"PUBLISHED","datePublished":"2026-06-09T07:42:48.028Z","dateUpdated":"2026-06-10T17:37:57.296Z","assignerShortName":"apache","assignerOrgId":"f0158376-9dc2-43b6-827c-5f631a4d8d09","dateReserved":"2026-06-01T17:37:44.180Z"},"containers":{"cna":{"title":"Apache Airflow Samba provider: Path traversal in GCSToSambaOperator via GCS object names","descriptions":[{"lang":"en","value":"The Apache Airflow Samba provider's `GCSToSambaOperator` joined GCS object names to the SMB destination path without a containment check, so an object named with `../` segments resolved a write path outside the configured `destination_path`.
