Summary
snowflake-connector-python vulnerable to insecure deserialization of the OCSP response cache
Details

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.
