Summary

TypeBot versions prior to 3.16.0 have incomplete SSRF protection for Webhook/HTTP Request blocks. Validation only checks hostname literals and IP formats but does not resolve DNS before allowing the request.

Risk Assessment

A hostname that resolves to 127.0.0.1, 169.254.169.254, or private RFC1918 addresses passes validation and is fetched by the backend HTTP client, enabling SSRF attacks to loopback, cloud metadata, and private networks.

Recommendation

Update TypeBot to version 3.16.0, which fixes this vulnerability.

Original NVD description (English source)

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.
