Possible fix(deps): 3 vulnerable dependencies in package-lock.json #266

Description

@begininvoke

Came across something in package-lock.json around line 4069 that looked worth flagging.

The vulnerability is real: fast-uri versions 2.3.1‑3.1.2 (and 4.0.0) fail to properly canonicalize Unicode IDN hostnames. The library’s IDN handling calls a helper that does not exist in the global URL constructor, leaving the host in its original Unicode form. This causes a mismatch between fast-uri’s normalize()/equal() results and what a WHATWG‑compatible parser (e.g., Node’s URL or fetch) would produce. Consequently, applications that enforce host‑based policies (denylists, loopback filters, redirect validation, outbound proxy routing) using fast-uri can be bypassed when the same URL later resolves to a different host after being processed by Node’s native parser. The fix is to upgrade fast-uri to a patched version (3.1.3 for the 3.x line, or 4.0.1 for the 4.x line).

Something like this might fix it:

--- a/package.json
+++ b/package.json
@@ -8,7 +8,7 @@
   "dependencies": {
-    "fast-uri": "3.1.2",
+    "fast-uri": "3.1.3",
    "other-package": "^1.2.3"
   }

For reference: rule CVE-2026-13676. Rated high.

I do not maintain this project, so I may well be missing context — if this is intentional or already handled elsewhere, please just close it.


Found with automated scanning (RedGem) and reviewed before opening. If it is not useful, closing it is completely fine.
