CVE-2026-13749Network attack vector

Arbitrary code execution via callback template injection

Published Jun 29, 2026 · Updated Jun 29, 2026

Code injection in Snowflake CLI before 3.19.0 allows context-dependent attackers to execute arbitrary code via crafted project content. The Snowpark annotation processor callback template interpolates attacker-controlled project values into generated Python code without neutralization, which the CLI executes during bundling or deployment. Exploitation requires a user to run the affected workflow on attacker-controlled content, and the code runs with that user's local privileges.
