Slack incoming webhook URL in client code

What this rule means

A https://hooks.slack.com/services/T*/B*/... URL was found in your client.

Why it matters

Anyone with the URL can post to that Slack channel. Common abuse: post phishing links impersonating internal alerts.

How to fix it

  1. Disable the webhook in Slack → app settings → Incoming Webhooks → delete.
  2. Use Block Kit + bot tokens server-side for richer formatting and better security.
