  • OutputFile Linear triage issue for unapproved editLinearLinear

What it does

Turns Cloudflare WAF edits into immediate triage work. Instead of waiting for a nightly scan, it listens for Cloudflare audit-log events in real time, decides whether the rule change was sanctioned, and opens a triage issue in Linear the moment an unapproved edit lands.

When to use it

Use it when minutes matter and a nightly diff is too slow. Ideal for teams who want an immediate signal whenever someone touches firewall rules outside the change window, so an attacker-opened hole or a fat-fingered rule gets investigated right away.

How it works

  1. 1A Cloudflare audit-log webhook delivers a firewall-rule change event.
  2. 2The workflow re-reads the affected zone's WAF rules from Cloudflare to capture the full new state.
  3. 3A logic step compares the actor and change against an allowlist of approved change-window operators.
  4. 4Sanctioned edits are recorded and the flow ends; unsanctioned edits continue.
  5. 5A Linear issue is created with the rule diff, actor, and timestamp, labeled for security triage and assigned to the on-call reviewer.
