Description
The Exasol JDBC driver previously included file content in error messages when an invalid file was specified as the host in the connection string. This behavior could result in the unintentional disclosure of file contents in environments relying on cloud-based multi-tenant BI platforms.
Workaround
Users are advised not to use files in the connection string until the updated driver version is in place.
Fix
The error handling has been updated to ensure sensitive file contents are not included in error messages. Moving forward, error messages will only display the file name and a concise description of the issue.
Error: The file 'file.txt' contains invalid entries. The file should only include valid hostnames.
This update provides clearer error messaging while removing unintended file content exposure.
