Details
As written in the advisory (Markdown source, shown as plain text).
### Issue
Snowflake discovered and remediated a vulnerability in the Snowflake JDBC Driver. On Linux systems, when temporary credential caching is enabled, the Snowflake JDBC Driver will cache temporary credentials locally in a world-readable file.
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. In the vulnerable versions of the Driver, this file is created with world-readable permissions.
### Solution
Snowflake released version 3.22.0 of the Snowflake JDBC Driver, which fixes this issue. We recommend users upgrade to version 3.22.0.
