I think there may be a problem in sideshow-term/package-lock.json around line 649.
fast-uri 3.1.2 does not correctly canonicalize Unicode (IDN) hostnames for HTTP URLs. An attacker can supply a URL with a non‑ASCII host that fast-uri treats as a different hostname than Node's built‑in URL parser, allowing bypass of host‑based security checks (e.g., deny‑lists, loopback filters, redirect validation). This can lead to unauthorized outbound connections or request forgery, which is why the CVE is rated HIGH.
Something like this might fix it:
