CVE-2026-13748 | Snowflake CLI Arbitrary Local File Read and Exfiltration Through Improper File Path Restriction

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.

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:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
