CVE-2026-73530
7.7 ÉlevéeDescription
Flyto2 Core before 2.28.0 contains a server-side request forgery guard bypass vulnerability that allows attackers to reach internal services by supplying URLs using the unblocked IPv6 address `::` which the kernel routes to loopback identically to `0.0.0.0`. Attackers can submit requests or trigger 302 redirects to ` to bypass the private IP range and blocked hostname checks in `is_private_ip()`, reaching services bound to IPv6 loopback across the `http.get`, `http.request`, and `http.batch` modules.
