CVE-2023-25691Network attack vector

Remote code execution via proxy version path

Published Feb 24, 2023 · Updated Mar 11, 2025

Improper input validation in Apache Airflow Google Provider before 8.10.0 allows remote attackers to execute code through Cloud SQL proxy downloads. CloudSqlProxyRunner inserts an unvalidated sql_proxy_version value into a Google Storage path, writes the response to disk, marks it executable, and launches it. Exploitation requires control of that connection value and a reachable attacker-supplied object; code runs with the Airflow task process privileges.
