CVE-2022-46725

What it actually does

Improper input validation in URL handling allows crafted inputs to bypass checks and display spoofed addresses in the UI.

Why it matters to the business

Users may be misled into believing they are on a legitimate site, increasing risk of phishing or credential theft with moderate operational exposure due to high ecosystem prevalence in dependent packages.

How an attack unfolds

An attacker hosts a malicious site with a specially crafted URL that exploits weak validation; when visited, the address bar shows a trusted domain instead of the real destination, tricking the user without requiring authentication or interaction beyond navigation.

How to fix it

Upgrade affected Node.js instances to the fixed commit 4b2085feacefb755e6106a38e179ed6076611d19 or later; apply vendor patches for iOS 16.4 and iPadOS 16.4 equivalents where applicable; validate URL parsing logic in custom handlers.

How to confirm the fix worked

Confirm deployment of commit 4b2085feacefb755e6106a38e179ed6076611d19; test with known spoofing URL payloads to ensure address bar reflects actual destination; review changelog for input validation improvements.

Typical attack path

1. Craft malicious URL with spoofed components that evade input validation
2. Host or deliver the URL via phishing or compromised site
3. Victim visits the URL in an affected client
4. Address bar displays falsified origin, enabling further social engineering

How to detect it

Review web server and browser logs for visits to domains with anomalous URL structures; search proxy or application logs for repeated navigation attempts that match known spoof patterns; examine client-side rendering artifacts for address bar discrepancies.

What your security team should do

• Prioritize patching Node.js to the listed fixed commit within 30 days given stable but non-zero EPSS
• Audit all downstream dependents for the vulnerable URL handling code
• Implement additional client-side URL canonicalization checks
• Monitor for unusual navigation patterns in web-facing applications
