FKIE_CVE-2026-85528

Vulnerability from fkie_nvd - Published: 2026-09-04 09:17 - Updated: 2026-09-04 20:17
Severity
5.3 (Medium) - CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N
Summary
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.
