CVE-2026-67428Public exploitNetwork attack vector

Authenticated SSRF via unguarded outbound request modules

Published Jul 29, 2026 · Updated Jul 29, 2026

Server-side request forgery in Flyto2 Core before 2.26.7 allows remote authenticated users to access internal services via crafted URLs. Multiple HTTP-emitting modules issue outbound requests to caller-controlled destinations without invoking validate_url_with_env_config and return response bodies. Workflow-author credentials are required; exploitation can read cloud metadata and internal responses or send requests to internal APIs.
