CVE-2026-86597

Summary

Insertion of sensitive information into log files in the Snowflake Python, Go, JDBC, Node.js, PHP PDO, and ODBC drivers allowed authentication tokens, query-result encryption keys, pre-signed cloud-storage URLs, and SAML assertions to be written to diagnostic logs in circumstances where the available log redaction did not cover all affected log paths and data types. An attacker with read access to the log destination, whether the local filesystem, a log aggregation service, or a CI/CD artifact store, could obtain credentials and decryption keys that, if still valid at the time of access, could be used to authenticate to the corresponding Snowflake account or cloud-storage object. Successful exploitation requires read access to the log destination, and impact is bounded by credential lifetime and object scope. The fix is available in the patched versions listed above. Users must manually upgrade and should securely delete previously generated diagnostic logs containing sensitive information where retention is not required.
