Short explanation
Multiple Snowflake client drivers contain a vulnerability due to missing origin validation in the local loopback callback listener used for the external browser single sign-on flow. This flaw may allow an attacker to interfere with a user's login attempt and cause the authentication process to fail.
Organizations using the affected client drivers face the risk of disrupted authentication flows and blocked login attempts.
What should be done?
- Follow vendor advisories to apply updates
- Manually upgrade affected drivers
- Migrate to the latest major version of the module for Go v1 users

Show the technical text from the sources
Multiple Snowflake client drivers implementing the `authenticator=externalbrowser` single sign-on flow could have allowed an attacker to interfere with a user's login attempt through weaknesses in the local loopback callback listener used to receive the identity provider's response. The listener reflected an arbitrary request's Origin header into its CORS response headers and accepted the first token-bearing request it received during the login window without verifying a CSRF state value bound to that specific login attempt. An attacker able to reach the listener during an active login might have leveraged this to submit a forged callback response, causing the authentication attempt to fail. The fix is available in Snowflake Connector for Python 4.8.0, Snowflake Go Driver v2.3.0, Snowflake JDBC Driver 4.4.0 (including the snowflake-jdbc-fips and snowflake-jdbc-thin artifacts), Snowflake Node.js Driver 3.4.0, Snowflake Connector for .NET 6.3.0, Snowflake ODBC Driver 4.0.0, Snowflake PHP PDO Driver 4.3.0, and libsnowflakeclient 2.11.1. Go v1 users must migrate to the latest major version of the module. Users must manually upgrade.
