Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Snowflake JDBC driver (net.snowflake:snowflake-jdbc) versions 3.2.6 through 3.19.1 are affected. Data uploaded to an encrypted stage can lack the additional client-side encryption layer when the CLIENT_ENCRYPTION_KEY_SIZE parameter is set to 256 on Azure or GCP accounts. The source does not describe an attacker's required access; it states that the impact is that data is protected only by TLS in transit and server-side encryption at rest. Upgrade to version 3.20.0 or later.
