CVE-2026-49213Public exploitNetwork attack vector

Authenticated SSRF via unblocked IPv6 unspecified address

Published Jul 10, 2026 · Updated Jul 10, 2026

SSRF in Typebot before 3.17.2 allows remote authenticated users to access local HTTP services via an IPv6 unspecified address. The shared validateHttpReqUrl validator passes :: and its expanded form to safeKy because validateIPAddress omits the IPv6 unspecified range. Workspace editor or creator access is required to configure the server-side request, which can read responses or invoke state-changing local endpoints.
