CVE-2026-3293 Details
Description
A weakness has been identified in snowflakedb snowflake-jdbc up to 4.0.1. Impacted is the function SdkProxyRoutePlanner of the file src/main/java/net/snowflake/client/internal/core/SdkProxyRoutePlanner.java of the component JDBC URL Handler. Executing a manipulation of the argument nonProxyHosts can lead to inefficient regular expression complexity. The attack can only be executed locally. The exploit has been made available to the public and could be used for attacks. This patch is called 5fb0a8a318a2ed87f4022a1f56e742424ba94052. A patch should be applied to remediate this issue.
A denial-of-service vulnerability has been identified in the Snowflake JDBC driver, specifically in versions through 4.0.1. The issue arises in the SdkProxyRoutePlanner class, where the nonProxyHosts parameter can be manipulated to create inefficient regular expressions. This vulnerability leads to catastrophic backtracking and CPU exhaustion. The problem is triggered by supplying crafted nonProxyHosts values via the JDBC URL, which are then used in regular expression evaluations that can be exploited to cause significant performance degradation.
Users are advised to update to Snowflake JDBC version 4.0.1 or later, where this vulnerability has been fixed.
