CVE-2026-67530

WACRM is a self-hostable CRM template for WhatsApp. In 0.7.0 and earlier, the automation send_webhook action in src/lib/automations/engine.ts and its validation in src/lib/automations/validate.ts allowed an authenticated user with automation privileges to submit an arbitrary webhook URL that the server fetched without the existing isDeliverableUrl SSRF guard in src/lib/webhooks/ssrf.ts, allowing requests to private, loopback, link-local, or cloud metadata addresses such as the cloud metadata endpoint at 169.254.169.254. This vulnerability is fixed with commit 23838a9959550e975d732ae08a44a3a2f0cc084b.
