CVE-2025-27496: Snowflake Jdbc

Low severity, CVSS 3.3. EPSS: 0.1% chance of exploitation in the next 30 days.

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.

Affected products

• Snowflake Snowflake Jdbc: from 3.0.13, before 3.23.1 (fixed in 3.23.1)
