AVID-2026-R1671

Description

Snowflake JDBC Driver client-side encryption key in DEBUG logs (CVE-2025-27496)

Details

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.

Reason for inclusion in AVID: The CVE describes a vulnerability in the Snowflake JDBC driver where DEBUG logging could exfiltrate the client-side encryption master key. This is a software supply-chain vulnerability affecting a dependency commonly used in AI/data pipelines to access Snowflake data, thus impacting AI workloads. It is a security vulnerability with potential data exposure, and the report provides affected versions and a fix. Therefore it meets AVID criteria for AI-related, GPAI supply-chain, and security impact with sufficient evidence.
