Inclusion of Sensitive Information in Snowflake JDBC

1) Inclusion of Sensitive Information in Log Files

EUVDB-ID: #VU112020

Risk: Low

CVSSv4.0: 1.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2025-27496

CWE-ID: CWE-532 - Information Exposure Through Log Files

Exploit availability: No

Description

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to the Driver would log locally the client-side encryption master key of the target stage during the execution of GET/PUT commands when the logging level was set to DEBUG. This key by itself does not grant access to any sensitive data without additional access authorizations, and is not logged server-side by Snowflake. A local user can read the log files and gain access to sensitive data.

Mitigation

Install update from vendor's website.
