Snowflake Snowpark Python SDK是美国Snowflake公司的一系列Python软件开发工具包。 Snowflake Snowpark Python SDK 1.53.0之前版本存在SQL注入漏洞，该漏洞源于SQL注入问题，可能导致经过身份验证的低权限用户通过在源数据库列名中嵌入SQL有效载荷、提供特制location参数将COPY INTO重定向到任意源查询，或在导出路径中包含反斜杠单引号序列绕过normalize_path()清理器并通过DataFrame.to_csv()注

Vulnerability Title
SQL Injection in Snowflake Snowpark Python SDK
Source: CVE Program / CVE List V5
Vulnerability Description
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.
