Which packages are affected by GHSA-m4f6-vcj4-w5mx?

GHSA-m4f6-vcj4-w5mx affects the following packages: snowflake-connector-python (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-m4f6-vcj4-w5mx?

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-m4f6-vcj4-w5mx is resolved across your whole dependency graph.

How do I detect GHSA-m4f6-vcj4-w5mx in my PyPI dependencies?

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.

How do I mitigate GHSA-m4f6-vcj4-w5mx if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-m4f6-vcj4-w5mx?

O3 pinpoints whether GHSA-m4f6-vcj4-w5mx is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-m4f6-vcj4-w5mx actively exploited in the wild?

No public exploit code has been indexed for GHSA-m4f6-vcj4-w5mx yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-m4f6-vcj4-w5mx?

GHSA-m4f6-vcj4-w5mx has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 14th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-m4f6-vcj4-w5mx?

GHSA-m4f6-vcj4-w5mx is classified as Deserialization of Untrusted Data (CWE-502). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-m4f6-vcj4-w5mx published, and has it been updated?

GHSA-m4f6-vcj4-w5mx was published on January 29, 2025 and was last updated on February 4, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Issue

Snowflake discovered and remediated a vulnerability in the Snowflake Connector for Python. The OCSP response cache uses pickle as the serialization format, potentially leading to local privilege escalation.

This vulnerability affects versions 2.7.12 through 3.13.0. Snowflake fixed the issue in version 3.13.1.

Vulnerability Details

The OCSP response cache is saved locally on the machine running the Connector using the pickle serialization format. This can potentially lead to local privilege escalation if an attacker has write access to the OCSP response cache file.

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.
