CVE-2026-38527Public exploitNetwork attack vector

Authenticated internal scanning via unvalidated webhook URL

Published Apr 14, 2026 · Updated Apr 14, 2026

SSRF in Webkul Krayin CRM 2.2.x allows remote authenticated users to scan internal resources through crafted webhook requests. WebhookRequest stores the end_point value without validating its scheme, host, or address, and WebhookService later requests that destination. Any valid CRM user must create and trigger the webhook; errors or timing reveal internal services, while reachable IMDSv1 endpoints expose cloud credentials.
