MODERATECVE-2025-24794 is a MODERATE (CVSS 6.7) snowflake-connector-python vulnerable to insecure deserialization vulnerability (CWE-502: Deserialization of Untrusted Data) affecting Snowflake connector python libraries in the PyPI ecosystem. The issue involves snowflake-connector-python vulnerable to insecure deserialization of the ocsp response cache. Remediation is available by upgrading affected packages to version 3.13.1.
CVE-2025-24794 at a Glance
Security Impact
CVSS: 6.7
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
How to Fix CVE-2025-24794
To remediate this vulnerability, upgrade all affected Snowflake connector python dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
pip install snowflake-connector-python>=3.13.1
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
pip show snowflake-connector-python
How to Check if You Are Affected
To determine whether your Python environment is affected by CVE-2025-24794, inspect your installed packages using pip:
pip show snowflake-connector-python
Analyze the terminal output to locate any version of Snowflake connector python in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.13.1), your application is affected.
Note: The pip show snowflake-connector-python command checks currently installed packages in your active Python environment.
Technical Details
Vulnerability Mechanism & Technical Analysis

"details" : "### Issue\nSnowflake 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.\n\nThis vulnerability affects versions 2.7.12 through 3.13.0. Snowflake fixed the issue in version 3.13.1.\n\n### Vulnerability Details\nThe 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.\n\n### Solution\nSnowflake released version 3.13.1 of the Snowflake Connector for Python, which fixes this issue. We recommend users upgrade to version 3.13.1.\n\n### Additional Information\nIf you discover a security vulnerability in one of our products or websites, please report the issue to HackerOne.
