The IDN conversion path calls a helper that does not exist on the global URL constructor, silently leaving the host in its original Unicode form while normalize() and equal() still return values that differ from a WHATWG-compatible URL parser. Applications that use fast-uri to enforce host-based policy (denylists, loopback filtering, redirect validation, outbound proxy routing) before passing the same URL to Node's URL or fetch can be bypassed when the two implementations resolve the same input to different hosts. Patches: upgrade to fast-uri 3.1.3 for the 3.x line or 4.0.1 for the 4.x line. Workarounds: enforce host policy using the same URL parser used for the actual request, or reject non-ASCII hosts before policy checks.","severity":{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-11","score":0.00692,"percentile":0.53324,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-436","CWE-551"],"published":"2026-06-29T13:22:44Z","modified":"2026-11-05T11:15:11Z","fixes":[{"ecosystem":"npm","package":"fast-uri","fixed_in":["4.0.1","3.1.3","2.4.2"],"sources":["ghsa","osv"]},{"ecosystem":"TuxCare:npm","package":"fast-uri","fixed_in":["3.0.6-tuxcare.3"],"sources":["osv"]},{"ecosystem":"Debian:14","package":"node-ajv","fixed_in":["8.20.0~ds+~cs7.1.2-1"],"sources":["osv"]},{"ecosystem":"Root:npm","package":"fast-uri","fixed_in":["3.0.1-aikido.3","3.0.1-aikido.4","3.0.1-aikido.5","3.0.2-aikido.6","3.1.0-aikido.6","3.0.6-aikido.5","3.1.2-aikido.3","3.0.1-aikido.6","3.0.3-aikido.3","3.0.6-aikido.3","3.1.0-aikido.3","3.1.2-aikido.1","3.0.1-aikido.7","3.0.6-aikido.4","3.1.0-aikido.5","3.1.2-aikido.2","3.0.2-aikido.2","3.0.2-aikido.3","3.0.2-aikido.4","3.0.2-aikido.5","3.0.3-aikido.5","3.0.6-aikido.6","3.0.3-aikido.6","3.0.3-aikido.7","3.0.1-aikido.8","3.0.3-aikido.8","3.1.2-aikido.4","3.0.3-aikido.9","3.1.3-aikido.2","3.1.3-aikido.3"],"sources":["osv"]},{"ecosystem":"Root:npm","package":"@rootio/fast-uri","fixed_in":["3.0.1-root.io.3","3.0.1-root.io.4","3.0.1-root.io.5","3.0.2-root.io.6","3.1.0-root.io.6","3.0.6-root.io.5","3.1.2-root.io.3","3.0.1-root.io.6","3.0.3-root.io.3","3.0.6-root.io.3","3.1.0-root.io.3","3.1.2-root.io.1","3.0.1-root.io.7","3.0.6-root.io.4","3.1.0-root.io.5","3.1.2-root.io.2","3.0.2-root.io.2","3.0.2-root.io.3","3.0.2-root.io.4","3.0.2-root.io.5","3.0.3-root.io.5","3.0.6-root.io.6","3.0.3-root.io.6","3.0.3-root.io.7","3.0.1-root.io.8","3.0.3-root.io.8","3.1.2-root.io.4","3.0.3-root.io.9","3.1.3-root.io.2","3.1.3-root.io.3"],"sources":["osv"]},{"ecosystem":"openSUSE:Tumbleweed","package":"python-pydata-sphinx-theme","fixed_in":["0.19.0-2.1"],"sources":["osv"]},{"ecosystem":"openSUSE:Leap

The IDN conversion path calls `URL.domainToASCII(...)` on the global WHATWG `URL` constructor, where that helper does not exist. The resulting `TypeError` is silently routed into `parsed.error`, but `parse()`, `normalize()`, and `equal()` all return with the host left in its original Unicode form.\n\nFor example, `http://127。0。0。1/` is treated by `fast-uri` as host `127。0。0。1`, while Node's WHATWG URL parser and `fetch()` canonicalize the same input to `127.0.0.1`.\n\nApplications that use `fast-uri` to enforce host-based policy (denylists, loopback filtering, redirect validation, outbound proxy routing) before passing the same URL into Node's URL or `fetch()` consumers see a policy/use desync and can be steered to an unintended destination.\n\n### Patches\n\nUpgrade to `fast-uri` v4.0.1, v3.1.3, or v2.4.2\n\n### Workarounds\n\nNone.
