CVE-2026-50203
Last modified
CVE-2026-50203 is a critical-severity vulnerability rated 9.1/10 on the CVSS scale. A path traversal in the SFTP provider (`SFTPHook.retrieve_directory` / `SFTPOperator(operation=get)`) let a malicious or compromised remote SFTP server write files outside the configured local destination directory via crafted directory-entry names. No Airflow account is required — the attack surface is any deployment downloading directories from an untrusted SFTP server. EPSS estimates a 0.63% chance of exploitation in the next 30 days.
