EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-r2x6-cjg7-8r43 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 379,145 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Issue
Snowflake discovered and remediated a vulnerability in the Snowflake Connector for Python. On Linux systems, when temporary credential caching is enabled, the Snowflake Connector for Python will cache temporary credentials locally in a world-readable file.
This vulnerability affects versions 2.3.7 through 3.13.0. Snowflake fixed the issue in version 3.13.1.
Vulnerability Details
On Linux, when either EXTERNALBROWSER or USERNAME_PASSWORD_MFA authentication methods are used with temporary credential caching enabled, the Snowflake Connector for Python will cache the 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 3.13.1 of the Snowflake Connector for Python, which fixes this issue. We recommend users upgrade to version 3.13.1.

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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update snowflake-connector-python to 3.13.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r2x6-cjg7-8r43 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-r2x6-cjg7-8r43 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-r2x6-cjg7-8r43. 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-r2x6-cjg7-8r43 in your dependencies?
O3 Security finds GHSA-r2x6-cjg7-8r43 across PyPI dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
