{"id":"CVE-2026-85528","state":"PUBLISHED","title":"Snowflake JDBC Driver auto-configuration account validation permits credential redirection","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.","publishedAt":"2026-09-04T08:36:28.553Z","updatedAt":"2026-09-10T15:49:41.523Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","source":"SNOWFLAKE"},"assigner":"SNOWFLAKE","products":["Snowflake Snowflake JDBC Driver","Snowflake Snowflake JDBC Driver (FIPS)","Snowflake Snowflake JDBC Driver (Thin)"],"affected":[{"vendor":"Snowflake","product":"Snowflake JDBC Driver","packageName":"net.snowflake:snowflake-jdbc","defaultStatus":"unaffected","versions":[{"version":"4.2.0","status":"affected","lessThan":"4.3.4","versionType":"maven"}],"collectionURL":"https://repo.maven.apache.org/maven2","repo":"https://github.com/snowflakedb/snowflake-jdbc"},{"vendor":"Snowflake","product":"Snowflake JDBC Driver (FIPS)","packageName":"net.snowflake:snowflake-jdbc-fips","defaultStatus":"unaffected","versions":[{"version":"4.2.0","status":"affected","lessThan":"4.3.4","versionType":"maven"}],"collectionURL":"https://repo.maven.apache.org/maven2","repo":"https://github.com/snowflakedb/snowflake-jdbc"},{"vendor":"Snowflake","product":"Snowflake JDBC Driver (Thin)","packageName":"net.snowflake:snowflake-jdbc-thin","defaultStatus":"unaffected","versions":[{"version":"4.2.0","status":"affected","lessThan":"4.3.4","versionType":"maven"}],"collectionURL":"https://repo.maven.apache.org/maven2","repo":"https://github.com/snowflakedb/snowflake-jdbc"}],"references":["https://docs.snowflake.com/en/release-notes/clients-drivers/jdbc-2026#version-434-sep-03-2026"],"weaknesses":["CWE-20","CWE-918"],"ingestedAt":"2026-10-29T20:13:15.269Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/85xxx/CVE-2026-85528.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-85528","state":"PUBLISHED","datePublished":"2026-09-04T08:36:28.553Z","dateUpdated":"2026-09-10T15:49:41.523Z","assignerShortName":"SNOWFLAKE","assignerOrgId":"412d305a-227d-44f9-a262-a31ba44f2aea","dateReserved":"2026-09-04T08:34:57.842Z"},"containers":{"cna":{"title":"Snowflake JDBC Driver auto-configuration account validation permits credential redirection","descriptions":[{"lang":"en","value":"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.
