CVE-2025-46330: Snowflake Connector For C/c++

Low severity, CVSS 3.3. EPSS: 0.2% chance of exploitation in the next 30 days.

libsnowflakeclient is the Snowflake Connector for C/C++. Versions starting from 0.5.0 to before 2.2.0, incorrectly treat malformed requests that caused the HTTP response status code 400, as able to be retried. This could hang the application until SF_CON_MAX_RETRY requests were sent. This issue has been patched in version 2.2.0.

Affected products

• Snowflake Connector For C/c++: from 0.5.0, before 2.2.0 (fixed in 2.2.0)
