Description

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.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for net.snowflake:snowflake-jdbc, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update net.snowflake:snowflake-jdbc to 3.22.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-33g6-495w-v8j2 is resolved across your whole dependency graph.

  3. Workarounds

    Close the privilege gap rather than the entry point: audit which accounts, roles and service identities can reach the affected operation, drop the component to the least privilege it actually needs, and review file and directory permissions created by earlier installs — a default left in place is what makes this reachable.
