Technical details

The Snowflake Spark Connector (spark-snowflake) prior to version 3.2.1 is affected by multiple input validation flaws including SQL Injection (CWE-89), Server-Side Request Forgery (CWE-918), and Confused Deputy (CWE-441) vulnerabilities. Attackers can exploit these by crafting malicious OAuth token request URLs, injecting SQL via staging options in shared Spark environments, or using runtime SET commands to override trusted catalog connection options. Successful exploitation allows for the exfiltration of OAuth client credentials, execution of arbitrary SQL under the connector's role, or redirection of COPY operations to attacker-controlled storage. The issues were addressed in version 3.2.1 by restricting the fallback catalog to immutable configurations, improving identifier quoting, and adding URL scheme/host validation.
