Server side request forgery in Apache Impala versions 4.4.x and 4.5.x. Authenticated Impala users with permissions to execute the ai_generate_text() function can exfiltrate secrets provided by the credential providers configured in the `hadoop.security.credential.provider.path` property of `core-site.xml`. The secret's key must be known to the user.
