GHSA-q298-375f-5q63 — low GitHub Advisory (CVE-2025-27496) in maven/net.snowflake:snowflake-jdbc

Description

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.

3.3	3.1	—	`CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N` Click to expand Attack vector (AV:L) They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by. Attack complexity (AC:L) Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup. Privileges required (PR:L) A normal user session is enough; they don’t have to be admin. User interaction (UI:N) Nobody has to click “OK” or open a trap file; it can work without a victim helping. Scope (S:U) Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems. Confidentiality (C:L) Some sensitive info could get out, but not a total data dump. Integrity (I:N) Data isn’t meaningfully altered or forged. Availability (A:N) Service keeps running; no real outage angle.
