Slack app-level token

Part of Security, which counts for 30% of the overall score. When this check fires it deducts 15 points from that category, once per scan, no matter how many places it turns up.

What it detects

A Slack app-level token (xapp-...) was found. It is used for Socket Mode and org-level app operations.

Why it matters

A Slack app-level token is used for Socket Mode and org-level operations, so a leak can let an attacker connect as your app. It is a durable secret that belongs on the server only. Committing it also exposes the connection to your workspace events.

How to fix it

Store the app-level token in an environment variable or secret store and read it at runtime. Regenerate it in the Slack app configuration under Basic Information if exposed.
