CVE-2026-15183
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMultiple 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Snowflake Spark Connector (spark-snowflake) versions before 3.2.1 contain multiple input validation vulnerabilities allowing OAuth client credential exfiltration via crafted token request URLs, arbitrary SQL execution through staging options in shared Spark environments, and redirection of COPY operations to attacker-controlled storage. Attackers can inject SQL via runtime SET commands in shared Spark-SQL sessions to compromise the SnowflakeFallbackCatalog's option map, executing under cluster admin JDBC credentials.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify spark-snowflake connector versionLocate the spark-snowflake connector JAR in your Spark cluster's classpath or dependencies list (commonly in /usr/spark/jars/, /opt/spark/jars/, or your project's Maven/Spark dependencies), then run 'jar manifest' or check your dependency manager for the version attributeAffected if The installed version is earlier than 3.2.1 (for example, 3.1.5, 3.0.6, 2.x.x)
-
Confirm shared Spark environment usageDetermine whether the Spark cluster is shared among multiple users or tenants, which is required for the attacker to exploit the vulnerability in the summaryAffected if The connector runs in a multi-tenant or shared Spark environment where untrusted users can submit jobs
-
Review staging options in COPY operationsInspect any Snowflake COPY INTO statements or DataFrame write operations using the connector that include staging options (STAGE_STORAGE_INTEGRATION, STAGE_COPY_OPTIONS, or custom stage parameters)Affected if Staging options are exposed to users or allow external URL configurations that could be tampered with
-
Audit runtime SET command usageSearch Spark application code, notebooks, or job configurations for calls to the connector's SET method or runtime configuration options that populate the SnowflakeFallbackCatalog's option mapAffected if Runtime SET commands or dynamic option injection is used to configure the connector
-
Check SnowflakeFallbackCatalog configurationExamine the connector's catalog configuration for SnowflakeFallbackCatalog settings and verify whether cluster admin JDBC credentials are used for executionAffected if SnowflakeFallbackCatalog is enabled and executes under elevated cluster admin credentials accessible to shared environment users
You are affected if the spark-snowflake connector version is before 3.2.1 AND the environment is a shared Spark cluster where users can access staging options or use runtime SET commands to inject SQL through the SnowflakeFallbackCatalog.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade spark-snowflake to version 3.2.1 or later. Avoid shared Spark environments, implement strict input validation on all user-supplied options, and restrict OAuth token endpoint access.
spark-snowflake version 3.2.1
- Upgrade the spark-snowflake connector to version 3.2.1 or later in your project dependencies
- For Maven projects, update the dependency in pom.xml to <version>3.2.1</version> for artifact spark-snowflake
- For SBT projects, update the dependency to "net.snowflake:spark-snowflake_2.12:3.2.1" (or appropriate Scala version)
- For Gradle projects, update the dependency to implementation 'net.snowflake:spark-snowflake_2.12:3.2.1'
- Rebuild and redeploy your Spark application with the updated connector version
- Verify the upgrade does not introduce regressions in your data pipelines that use OAuth authentication, COPY operations, or staging options
