CVE-2026-15183— Input Validation Vulnerabilities in Snowflake Spark Connector

Quick assessment

Affected
Snowflake Snowflake Spark Connector
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Snowflake Snowflake Spark Connector是美国Snowflake公司的一个连接Apache Spark与Snowflake的数据处理插件。 Snowflake Spark Connector 3.2.1之前版本存在安全漏洞，该漏洞源于多个输入验证问题，可能导致攻击者窃取OAuth客户端凭据、以连接器的Snowflake角色执行任意SQL、或将COPY操作重定向到攻击者控制的存储。攻击者可通过提供特制的OAuth令牌请求URL、在摄取管道中放置恶意文件、在共享Spark环境中通

Vulnerability Title
Input Validation Vulnerabilities in Snowflake Spark Connector
Source: CVE Program / CVE List V5
Vulnerability Description
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.
