This vulnerability affects versions 3.6.8 through 3.21.0. Snowflake fixed the issue in version 3.22.0. Vulnerability Details On Linux, when either EXTERNALBROWSER or USERNAME_PASSWORD_MFA authentication methods are used with temporary credential caching enabled, the Snowflake JDBC Driver will cache temporary credentials in a local file.
