Detailsinfo

A vulnerability was found in Snowflake JDBC Driver up to 4.3.3. It has been classified as problematic. This affects some unknown functionality of the file connections.toml. The manipulation of the argument account with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on confidentiality. The summary by CVE is:

Improper input validation of the auto-configuration account identifier in Snowflake JDBC Driver versions 4.2.0 through 4.3.3 allowed a credential-bearing login request to be redirected to an attacker-selected HTTPS endpoint. An attacker able to control the account value could cause the driver to transmit a reusable login credential to a host of their choosing and replay it to obtain the privileges granted to that credential. Successful exploitation requires an application using jdbc:snowflake:auto with a connections.toml section that omits an explicit host and a lower-trust principal able to set the account value; ordinary JDBC URLs are unaffected. The fix is available in Snowflake JDBC Driver version 4.3.4. Users must manually upgrade.

It is possible to read the advisory at docs.snowflake.com. This vulnerability is uniquely identified as CVE-2026-85528 since 09/04/2026. The exploitability is told to be easy.
