Real-Time Risky Cloudflare WAF Change Auto-Block and Linear Ticket

Inspects each Cloudflare WAF change as it happens, and when a change matches risky patterns (rule disabled, action weakened, or scope broadened) it immediately re-applies…

How it runs

The automated pipeline, trigger to output.

  • TriggerCloudflare WAF change audit webhookHTTP webhook
  • LogicClassify change vs. prior value
  • LogicBranch on risky patterns (disabled/weakened/broadened)
  • ActionRe-apply prior safe value via CloudflareCloudflareCloudflare
  • OutputFile Linear ticket with reverted diff and risk reasonLinearLinear

What it does

Acts as an automated guardrail that reverses dangerous WAF edits the moment they land. If a change disables a protective rule, downgrades a block to log, or widens an allow scope, the flow restores the previous safe state and opens a tracked ticket explaining what was undone.

When to use it

Use it for high-sensitivity zones where certain WAF weakenings should never go live unreviewed, even briefly. Unlike an approval gate that waits, this enforces an opinionated safe-default and reverts first, then asks questions via a ticket.

How it works

  1. 1A Cloudflare audit webhook fires on a WAF or ruleset change.
  2. 2The flow compares the new rule state to the prior value to classify the change.
  3. 3A branch evaluates risky patterns: rule disabled, action downgraded to log/allow, or expanded IP/path scope.
  4. 4Safe or neutral changes are logged and pass through untouched.
  5. 5For a risky change, it immediately re-applies the prior safe value via the Cloudflare API.
  6. 6It files a Linear ticket capturing the actor, the reverted diff, and the risk reason, and tags the security team for follow-up.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect CloudflareWorkers, Pages, R2, KV — the edge stack.
  2. 2
    Connect LinearIssues, projects, cycles, triage.
  3. 3
    Connect HTTP webhookTrigger any URL on agent actions.
  4. 4
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  5. 5
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  6. 6
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
