Detailsinfo

A vulnerability has been found in Snowflake CLI up to 3.18.x and classified as problematic. This vulnerability affects some unknown functionality of the component Snowflake Service. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect confidentiality. CVE summarizes:

Improper restriction of file path resolution in Snowflake CLI versions prior to 3.19 allowed arbitrary local file content to be read and transmitted to Snowflake services. An attacker could exploit this by supplying crafted repository or project content that referenced files outside the intended project boundary, causing Snowflake CLI to read local files and upload or embed their contents during deployment or SQL template processing. Successful exploitation required the victim to process attacker-controlled project content, and retrieval of exfiltrated data depended on access to the victim's Snowflake account artifacts such as query history or uploaded stage content. The fix is available in Snowflake CLI version 3.19, and users must manually upgrade.

The advisory is shared for download at community.snowflake.com. This vulnerability was named CVE-2026-13748 since 06/29/2026. The exploitation appears to be easy. The attack needs to be approached locally. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1006.

Upgrading to version 3.19.0 eliminates this vulnerability.
