Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Snowflake JDBC Driver up to and including 4.0.1 is vulnerable to uncontrolled resource consumption through the SdkProxyRoutePlanner function, where a manipulated nonProxyHosts argument can lead to inefficient regular expression complexity. An attacker needs local access to trigger it, and a public exploit is reported. No fixed version is listed in the source, so the source suggests applying a patch, but it does not identify one.
