Description
Issue
Snowflake recently learned about and remediated a set of vulnerabilities in the Snowflake Connector for Python. Under specific conditions, certain users credentials (or portions of those credentials) were logged locally by the Connector to the users own systems. The credentials were not logged by Snowflake.
These vulnerabilities affect versions up to and including 3.12.2. Snowflake fixed the issue in version 3.12.3.
Vulnerability Details
When the logging level was set by the user to DEBUG, the Connector could have logged Duo passcodes (when specified via the “passcode” parameter) and Azure SAS tokens. Additionally, the SecretDetector logging formatter, if enabled, contained bugs which caused it to not fully redact JWT tokens and certain private key formats.
Solution
Snowflake released version 3.12.3 of the Snowflake Connector for Python, which fixes these issues. We recommend users upgrade to version 3.12.3 and review their logs for any potentially sensitive information that may have been captured.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for snowflake-connector-python. 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-connector-python to 3.12.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5vvg-pvhp-hv2m 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-5vvg-pvhp-hv2m 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-5vvg-pvhp-hv2m. 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-5vvg-pvhp-hv2m in your dependencies?
O3 detects GHSA-5vvg-pvhp-hv2m across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
