CVE-2026-13749: Improper Control of Generation of Code ('Code Injection') in Snowflake Snowflake CLI

VulnerabilityCVE-2026-13749cvecve-2026-13749
Published: 06/29/2026 (06/29/2026, 16:02:47 UTC)
Source: CVE Database V5
Vendor/Project: Snowflake
Product: Snowflake CLI

Description

Improper neutralization in the Snowpark annotation processor callback template in Snowflake CLI versions prior to 3.19 allowed arbitrary code execution during application bundling or deployment. An attacker could exploit this by supplying crafted project content that is interpolated into generated Python code, causing Snowflake CLI to execute attacker-controlled code in the local context of the user running the CLI. Successful exploitation requires the victim to run the relevant bundling or deployment workflow against attacker-controlled project content, and any resulting code runs with the privileges of that local execution context. The fix is available in Snowflake CLI version 3.19, and users must manually upgrade.
