CVE-2025-27496
Snowflake JDBC Driver client-side encryption key in DEBUG logs
Snowflake, a platform for using artificial intelligence in the context of cloud computing, has a vulnerability in the Snowflake JDBC driver ("Driver") in versions 3.0.13 through 3.23.0 of the driver. When the logging level was set to DEBUG, the Driver would log locally the client-side encryption master key of the target stage during the execution of GET/PUT commands. This key by itself does not grant access to any sensitive data without additional access authorizations, and is not logged server-side by Snowflake. Snowflake fixed the issue in version 3.23.1.

Snowflake JDBC Driver client-side encryption key in DEBUG logs
Issue
Snowflake discovered and remediated a vulnerability in the Snowflake JDBC driver (“Driver”). When the logging level was set to DEBUG, the Driver would log locally the client-side encryption master key of the target stage during the execution of GET/PUT commands. This key by itself does not grant access to any sensitive data without additional access authorizations, and is not logged server-side by Snowflake.
This vulnerability affects Driver versions 3.0.13 through 3.23.0. Snowflake fixed the issue in version 3.23.1.
Vulnerability Details
When the logging level was set to DEBUG, the Driver would locally log the client-side encryption master key of the target stage during the execution of GET/PUT commands. The key was logged in a JSON object under the queryStageMasterKey key. The key by itself does not grant access to any sensitive data.
Solution
Snowflake released version 3.23.1 of the Snowflake JDBC driver, which fixes this issue. We highly recommend users upgrade to version 3.23.1.
