CVE-2026-15062: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in Snowflake Snowpark Python SDK
SQL injection vulnerabilities in the Snowflake Snowpark Python SDK (snowpark-python) versions prior to 1.53.0 could allow authenticated low-privilege users to execute SQL beyond their authorization scope. An attacker could exploit these vulnerabilities by embedding SQL payloads in source database column names to escalate privileges via the DataFrameReader.dbapi() API by supplying a specially crafted location parameter to DataFrameWriter write methods to redirect a COPY INTO to an arbitrary source query, or by including a backslash-single-quote sequence in an export path to defeat the normalize_path() sanitizer and inject SQL via DataFrame.to_csv(). Successful exploitation may result in source database compromise, unauthorized cross-tenant data exfiltration, or unauthorized read of Snowflake account data.
AI Analysis
Technical Summary
This vulnerability in Snowflake Snowpark Python SDK (snowpark-python) prior to version 1.53.0 involves improper neutralization of special elements used in SQL commands, enabling SQL injection attacks. Authenticated users with low privileges can exploit this by embedding malicious SQL payloads in source database column names, manipulating the DataFrameReader.dbapi() API, supplying crafted location parameters to DataFrameWriter write methods to redirect COPY INTO commands, or injecting SQL via backslash-single-quote sequences in export paths to bypass path sanitization in DataFrame.to_csv(). These attack vectors can escalate privileges and lead to unauthorized data access or exfiltration across tenants and compromise of source databases.
Potential Impact
An attacker with valid authentication but low privileges can perform SQL injection attacks that allow execution of SQL commands beyond their authorized scope. This can result in compromise of the source database, unauthorized cross-tenant data exfiltration, and unauthorized reading of Snowflake account data. The vulnerability impacts confidentiality and integrity but does not affect availability.
Mitigation Recommendations
The vendor manages remediation for this cloud-hosted service. A patch is available in Snowpark Python SDK version 1.53.0 and later. Users should upgrade to version 1.53.0 or above to mitigate this vulnerability. Since this is a cloud service, Snowflake likely applies server-side mitigations; however, customers should verify their SDK versions and update accordingly. Patch status is confirmed as available.
