CVE-2026-6442	Apr 16, 2026	Snowflake Cortex Code CLI <1.0.25 Command Injection (CVE-2026-6442) Improper validation of bash commands in Snowflake Cortex Code CLI versions prior to 1.0.25 allowed subsequent commands to execute outside the sandbox. An attacker could exploit this by embedding specially crafted commands in untrusted content, such as a malicious repository, causing the CLI agent to execute arbitrary code on the local device without user consent. Exploitation is non-deterministic and model-dependent. The fix is automatically applied upon relaunch with no user action required.
CVE-2025-46329	Apr 29, 2025	libsnowflakeclient: DEBUG logs client key v0.5.0–2.2.0 (fixed) libsnowflakeclient is the Snowflake Connector for C/C++. Versions starting from 0.5.0 to before 2.2.0, are vulnerable to local logging of sensitive information. When the logging level was set to DEBUG, the Connector would log locally the client-side encryption master key of the target stage during the execution of GET/PUT commands. This key by itself does not grant access to any sensitive data without additional access authorizations, and is not logged server-side by Snowflake. This issue has been patched in version 2.2.0.

CVE-2025-46330	Apr 29, 2025	Retry Loop in libsnowflakeclient 0.5.0-<2.2.0 Causes Application Hang libsnowflakeclient is the Snowflake Connector for C/C++. Versions starting from 0.5.0 to before 2.2.0, incorrectly treat malformed requests that caused the HTTP response status code 400, as able to be retried. This could hang the application until SF_CON_MAX_RETRY requests were sent. This issue has been patched in version 2.2.0.	Connector For Cc
CVE-2025-46326	Apr 28, 2025	Snowflake Connector .NET 2.1.2-4.4.1 TOCTOU in Easy Logging snowflake-connector-net is the Snowflake Connector for .NET. Versions starting from 2.1.2 to before 4.4.1, are vulnerable to a Time-of-Check to Time-of-Use (TOCTOU) race condition. When using the Easy Logging feature on Linux and macOS, the Connector reads logging configuration from a user-provided file. On Linux and macOS, the Connector verifies that the configuration file can be written to only by its owner. That check was vulnerable to a TOCTOU race condition and failed to verify that the file owner matches the user running the Connector. This could allow a local attacker with write access to the configuration file or the directory containing it to overwrite the configuration and gain control over logging level and output location. This issue has been patched in version 4.4.1.	Snowflake Connector
CVE-2025-46327	Apr 28, 2025	TOCTOU in Snowflake's gosnowflake Driver before 1.13.3 (Linux, macOS) gosnowflake is the Snowflake Golang driver.

When using the Easy Logging feature on Linux and macOS the Driver reads logging configuration from a user-provided file. On Linux and macOS the Driver verifies that the configuration file can be written to only by its owner. That check was vulnerable to a TOCTOU race condition and failed to verify that the file owner matches the user running the Driver. This could allow a local attacker with write access to the configuration file or the directory containing it to overwrite the configuration and gain control over logging level and output location. This issue has been patched in version 2.0.4.	Snowflake Connector
CVE-2024-49750	Oct 24, 2024	Snowflake Connector <3.12.3: Logs expose Duo passcodes & Azure SAS tokens The Snowflake Connector for Python provides an interface for developing Python applications that can connect to Snowflake and perform all standard operations. Prior to version 3.12.3, when the logging level was set by the user to DEBUG, the Connector could have logged Duo passcodes (when specified via the `passcode` parameter) and Azure SAS tokens. Additionally, the SecretDetector logging formatter, if enabled, contained bugs which caused it to not fully redact JWT tokens and certain private key formats. Snowflake released version 3.12.3 of the Snowflake Connector for Python, which fixes the issue. In addition to upgrading, users should review their logs for any potentially sensitive information that may have been captured.	Snowflake Connector

CVE-2024-28851	Mar 15, 2024	Elevation-of-Privilege via Helper Script in Snowflake Hive MetaStore Connector The Snowflake Hive metastore connector provides an easy way to query Hive-managed data via Snowflake. Snowflake Hive MetaStore Connector has addressed a potential elevation of privilege vulnerability in a `helper script` for the Hive MetaStore Connector. A malicious insider without admin privileges could, in theory, use the script to download content from a Microsoft domain to the local system and replace the valid content with malicious code. If the attacker then also had local access to the same system where the maliciously modified script is run, they could attempt to manipulate users into executing the attacker-controlled helper script, potentially gaining elevated privileges to the local system. The vulnerability in the script was patched on February 09, 2024, without a version bump to the Connector. User who use the helper script are strongly advised to use the latest version as soon as possible. Users unable to upgrade should avoid using the helper script.	Snowflake Hive Metastore Connector
