{"id":"CVE-2026-85528","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-85528","generatedAt":"2026-10-28T02:10:17.770Z","title":"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.","description":"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, including the snowflake-jdbc-fips and snowflake-jdbc-thin. Users must manually upgrade.","published":"2026-09-04T09:17:12.000Z","lastModified":"2026-09-10T16:17:59.000Z","status":"Awaiting Analysis","sourceIdentifier":"412d305a-227d-44f9-a262-a31ba44f2aea","cvss":{"version":"3.1","score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-20","CWE-918"],"affected":[],"epss":{"score":0.0029,"percentile":0.21403,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.29%).
