### Summary A WEBHOOK alert channel stores a user-supplied `url`. When an alert fires (deployment/run failure, error groups), the webapp server (`alertsWorker` -> `DeliverAlertService`) POSTs the HMAC-signed alert payload to that URL via `fetch(webhook.url, ...)`. The URL is never validated against a host allowlist or private-IP/metadata blocklist (a repo-wide search for `169.254`, `isPrivate`, `isLoopback`, `net.isIP`, `ssrf` returns ZERO hits), and the API route's URL field is just `z.string().optional()` (no syntax check at all). So an authenticated tenant can point the webhook at internal infrastructure or `169.254.169.254` and the multi-tenant server fetches it. ### Affected `apps/webapp`, HEAD `5d99457` (current main). ### Root cause - Source (API route): `app/presenters/v3/ApiAlertChannelPresenter.server.ts` `ApiAlertChannelData.url = z.string().optional()` (no host validation); route `app/routes/api.v1.projects.$projectRef.alertChannels.ts` (PAT-auth). - Store: `app/v3/services/alerts/createAlertChannel.server.ts` persists `{url, secret, version}` verbatim. - Sink: `app/v3/services/alerts/deliverAlert.server.ts:973` `fetch(webhook.url, {method:"POST", headers:{"x-trigger

What to do next
- vendor patch
The original advisory lists fixed boundaries 4.5.2 for trigger.dev. Confirm the publisher’s latest guidance.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database via OSV
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
