Overview
snowflake-connector-python is a Snowflake Connector for Python
Affected versions of this package are vulnerable to Insertion of Sensitive Information into Log File via the logging process. An attacker can obtain authentication tokens, encryption keys, pre-signed URLs, and SAML assertions by accessing diagnostic logs that were insufficiently redacted. This is only exploitable if the attacker has read access to the log destination, such as the local filesystem, a log aggregation service, or a CI/CD artifact store.
