CVE-2026-15183
CriticalCVSS 9.2Exploitation Probability (EPSS)
Low risk11th percentile - higher than 11% of all known CVEs
Summary
Multiple input validation vulnerabilities in the Snowflake Spark Connector (spark-snowflake) prior to version 3.2.1 allow attackers to exfiltrate OAuth client credentials, execute arbitrary SQL with the connector's Snowflake role, or redirect COPY operations to attacker-controlled storage. Exploitation can occur via crafted OAuth token request URLs, malicious files in ingestion pipelines, SQL injection via staging options in shared Spark environments, or runtime SET commands in shared Spark-SQL sessions.
Risk Assessment
The risk includes theft of OAuth credentials, unauthorized access to Snowflake account data, and privilege escalation within connected infrastructure. Attackers can leverage shared Spark environments or crafted requests to compromise the connector.
Recommendation
Immediately upgrade the Snowflake Spark Connector to version 3.2.1 or later. Additionally, restrict access to shared Spark environments and monitor for unusual SQL queries and OAuth requests.
Original NVD description (English source)
Multiple input validation vulnerabilities in the Snowflake Spark Connector (spark-snowflake) versions prior to 3.2.1 can allow attackers to exfiltrate OAuth client credentials, execute arbitrary SQL with the connector's Snowflake role, or redirect COPY operations to attacker-controlled storage. 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. Successful exploitation may result in credential theft, unauthorized access to Snowflake account data, or privilege escalation within connected infrastructure.
