CVE-2023-28710Network attack vector

Arbitrary file read via crafted JDBC URL

Published Apr 7, 2023 · Updated Oct 22, 2024

Improper input validation in Apache Airflow Spark Provider before 4.0.1 allows remote attackers to read arbitrary files through JDBC. SparkJDBCHook concatenates connection host and schema values into a JDBC URL without rejecting path and query delimiters. Exploitation requires attacker-influenced JDBC connection fields to reach the hook and exposes files readable by the Airflow process.
