Description
Issue
Snowflake was informed via our bug bounty program of a command injection vulnerability in the Snowflake .NET driver via SSO URL authentication.
Impacted driver package:
snowflake-connector-net
Impacted version range:
before Version 2.0.18
Attack Scenario
In order to exploit the potential for command injection, an attacker would need to be successful in (1) establishing a malicious resource and (2) redirecting users to utilize the resource. The attacker could set up a malicious, publicly accessible server which responds to the SSO URL with an attack payload. If the attacker then tricked a user into visiting the maliciously crafted connection URL, the user’s local machine would render the malicious payload, leading to a remote code execution.
This attack scenario can be mitigated through URL whitelisting as well as common anti-phishing resources.
Solution
On December 2nd, 2022, Snowflake merged a patch that fixed a command injection vulnerability in the Snowflake .NET driver via SSO URL authentication. The vulnerability affected the Snowflake .NET driver before Version 2.0.18. We strongly recommend upgrading to the latest driver version as soon as possible via the following resources: Snowflake .NET Driver.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Snowflake.Data. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update Snowflake.Data to 2.0.18 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-223g-8w3x-98wr is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-223g-8w3x-98wr is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-223g-8w3x-98wr. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-223g-8w3x-98wr in your dependencies?
O3 detects GHSA-223g-8w3x-98wr across NuGet dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
