HIGH 8.8UPGRADE

CVE-2026-13749 is a high-severity flaw (CVSS 8.8) affecting snowflake cli. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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 requir

Timeline

snowflake snowflake cli UPGRADE
Affected: >= 2.4.0 and < 3.19.0
Fixed in: 3.19.0
Safe to downgrade to: a release before 2.4.0
1. Check installed version
apt-cache policy snowflake-cli || rpm -q snowflake-cli || snowflake-cli --version
2. UPGRADE to 3.19.0 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade snowflake-cli
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade snowflake-cli
Note
Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.
3. If no update is available yet, DOWNGRADE to a release before 2.4.0 (Debian / Ubuntu)
apt-cache madison snowflake-cli sudo apt install snowflake-cli=<VERSION_BEFORE_2.4.0> sudo apt-mark hold snowflake-cli
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list snowflake-cli sudo dnf downgrade snowflake-cli-<VERSION_BEFORE_2.4.0> sudo dnf versionlock add snowflake-cli
Downgrade risk
Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.
After downgrade
Restart the service, and keep the package held until a fixed release ships.
