Who should care

Users of Snowflake Spark Connector versions prior to 3.2.1, operators, platform administrators, vulnerability management teams, and security teams should apply the patch to prevent potential credential theft, unauthorized access to Snowflake account data, or privilege escalation within connected infrastructure.

Technical summary

The Snowflake Spark Connector (spark-snowflake) versions prior to 3.2.1 contains multiple input validation vulnerabilities. An attacker could exploit these vulnerabilities by supplying a crafted OAuth token request URL, placing malicious files in an ingestion pipeline, injecting SQL via staging options in a shared Spark environment, or issuing runtime SET commands in a shared Spark-SQL session to inject arbitrary SQL into the SnowflakeFallbackCatalog's option map, which executes under the cluster admin's JDBC credentials.
