CVE-2026-13749: Snowflake CLI Arbitrary Code Execution via Snowpark Annotation Processor Template Injection

Noroxi assessment

Priority: Monitor (action score 35/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.53% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: Snowflake Snowflake CLI 3.19.0.

Low priority for now. Upgrade to Snowflake Snowflake CLI 3.19.0 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
