An attacker who can modify the connection configuration can cause the driver to mint a fresh attestation and send it to a host they control. The captured token can be replayed to Snowflake for its remaining lifetime in accounts where that workload identity is already registered. On Azure, the token audience is also taken from connection configuration. Combined with an attacker-controlled host, the driver can request a Managed Identity access token scoped to a non-Snowflake Azure resource and deliver it to the attacker. That path is the only case in which impact extends beyond Snowflake; it is bounded by the token lifetime and the managed identity’s permissions. Successful exploitation requires WORKLOAD_IDENTITY authentication on a workload that already has an ambient cloud identity. Patched driver versions restrict this authenticator to recognized Snowflake hosts. Users must manually upgrade.", "affected": [ { "vendor": "Snowflake", "product": "Snowflake Connector for Python", "packageName": "snowflake-connector-python", "collectionURL": "https://pypi.org", "defaultStatus": "unaffected", "versions": [ { "version": "3.14.1", "status": "affected", "versionType": "python", "lessThan": "4.7.3" } ] }, { "vendor": "Snowflake", "product": "Snowflake Go Driver", "packageName": "github.com/snowflakedb/gosnowflake", "collectionURL": "https://pkg.go.dev", "defaultStatus": "unaffected", "versions": [ { "version": "1.15.0", "status": "affected", "versionType": "semver", "lessThanOrEqual": "1.19.1" } ] }, { "vendor": "Snowflake", "product": "Snowflake Go Driver", "packageName": "github.com/snowflakedb/gosnowflake/v2", "collectionURL": "https://pkg.go.dev", "defaultStatus": "unaffected", "versions": [ { "version": "2.0.0", "status": "affected", "versionType": "semver", "lessThan": "2.2.0" } ] }, { "vendor": "Snowflake", "product": "Snowflake JDBC Driver", "packageName": "net.snowflake:snowflake-jdbc", "collectionURL": "https://repo.maven.apache.org/maven2", "defaultStatus": "unaffected", "versions": [ { "version": "3.24.0", "status": "affected", "versionType": "maven", "lessThan": "4.3.4" } ] }, { "vendor": "Snowflake", "product": "Snowflake JDBC Driver (FIPS)", "packageName": "net.snowflake:snowflake-jdbc-fips", "collectionURL": "https://repo.maven.apache.org/maven2", "defaultStatus": "unaffected", "versions": [ { "version": "3.24.0", "status": "affected", "versionType": "maven", "lessThan": "4.3.4" } ] }, { "vendor": "Snowflake", "product": "Snowflake JDBC Driver (Thin)", "packageName": "net.snowflake:snowflake-jdbc-thin", "collectionURL": "https://repo.maven.apache.org/maven2", "defaultStatus": "unaffected", "versions": [ { "version": "3.24.0", "status": "affected", "versionType": "maven", "lessThan": "4.3.4" } ] }, { "vendor": "Snowflake", "product": "Snowflake Node.js Driver", "packageName": "snowflake-sdk", "collectionURL": "https://registry.npmjs.org", "defaultStatus": "unaffected", "versions": [ { "version": "2.1.1", "status": "affected", "versionType": "semver", "lessThan": "3.3.0" } ] }, { "vendor": "Snowflake", "product": "Snowflake Connector for .NET", "packageName": "Snowflake.Data", "collectionURL": "https://www.nuget.org", "defaultStatus": "unaffected", "versions": [ { "version": "4.7.0", "status": "affected", "versionType": "semver", "lessThan": "6.1.0" } ] }, { "vendor": "Snowflake", "product": "Snowflake ODBC Driver", "defaultStatus": "unaffected", "versions": [ { "version": "3.9.0", "status": "affected", "versionType": "semver", "lessThan": "3.20.0" } ] }, { "vendor": "Snowflake", "product": "Snowflake PHP PDO Driver", "defaultStatus": "unaffected", "versions": [ { "version": "3.6.0", "status": "affected", "versionType": "semver", "lessThan": "4.2.0" } ] }, { "vendor": "Snowflake", "product": "Snowflake Libsnowflakeclient", "defaultStatus": "unaffected", "versions": [ { "version": "2.2.0", "status": "affected", "versionType": "semver", "lessThan": "2.10.0" } ] } ] } } }
