CVE-2026-16870— Multiple Security Vulnerabilities in Snowflake libsnowflakeclient

Quick assessment

Affected
Snowflake Snowflake libsnowflakeclient
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 connector for c/c++是美国Snowflake公司的一个数据库连接程序。 Snowflake Connector for C/C++ 2.9.2之前版本存在安全漏洞，该漏洞源于文件下载路径中的栈缓冲区溢出和越界写入以及连接参数验证不当，可能导致远程代码执行、内存破坏和凭据外泄。

Vulnerability Title
Multiple Security Vulnerabilities in Snowflake libsnowflakeclient
Source: CVE Program / CVE List V5
Vulnerability Description
Multiple security vulnerabilities in Snowflake libsnowflakeclient versions prior to 2.9.2 could allow remote code execution and credential exfiltration. A stack-based buffer overflow in the file download path could allow remote code execution on a victim host. An attacker could exploit this by uploading a file with a crafted encryption metadata field to a shared internal stage that a victim process later downloads, and impact would be limited to deployments where principals with different privilege levels share the same internal stage. A related out-of-bounds write in the same download path could allow memory corruption with attacker-controlled write primitives. An attacker may exploit this through a crafted initialization vector metadata field on a shared stage, and impact would be limited by the same stage-write precondition. Improper validation of connection parameters could allow an attacker-controlled input to redirect outbound authentication requests — including credentials and tokens — to an attacker-controlled endpoint. Impact is limited to embedding deployments where a lower-privileged principal can influence connection configuration while higher-privileged service credentials are in use. The fix is available in Snowflake libsnowflakeclient version 2.9.2. The Snowflake PHP PDO Driver and Snowflake ODBC Driver embed the affected library; fixes are available in versions 4.1.0 and 3.19.0 respectively. Users must manually upgrade.
