Square access 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 Square OAuth/access token (sq0atp-/sq0csp-/sq0idp-...) was found. It can read and act on the connected Square account.
Why it matters
A Square access token can read and act on the connected Square account, including payments and customer data. A leak is a financial and privacy risk. The token is long-lived until revoked.
How to fix it
Move the token into a server-side environment variable and read it at runtime; keep it off the client. Revoke the exposed token and issue a new one in the Square developer dashboard. Prefer OAuth with the least scopes needed.
