CVE-2026-34207 Details
Description
TypeBot is a chatbot builder tool. In versions prior to 3.16.0, SSRF protection for Webhook / HTTP Request blocks validates only the URL string, blocked hostname literals, and literal IP formats. It does not resolve DNS before allowing the request. As a result, a hostname such as ssrf-repro.example that resolves to 127.0.0.1, 169.254.169.254, or RFC1918/private space passes validation and is later fetched by the backend HTTP client. This enables server-side request forgery to loopback, cloud metadata, and private network targets. This issue has been resolved in version 3.16.0.
A server-side request forgery (SSRF) vulnerability has been identified in TypeBot versions prior to 3.16.0. The issue arises because the SSRF protection for Webhook and HTTP Request blocks only validates the URL string, blocking certain hostname literals and IP formats, but does not resolve DNS before allowing requests. This oversight enables hostnames that resolve to loopback, cloud metadata, or private network IPs to bypass validation and be fetched by the backend HTTP client. As a result, sensitive data could be exfiltrated or internal services could be accessed inappropriately.
Users can update to TypeBot version 3.16.0 or later, where this vulnerability has been fixed.
