Improper Input Validation in url-js

Description

The package url-js before 2.1.0 is vulnerable to Improper Input Validation due to improper parsing, which makes it is possible for the hostname to be spoofed. http://\\\\localhost and http://localhost are the same URL. However, the hostname is not parsed as localhost, and the backslash is reflected as it is.

Recommendation

Update the url-js package to the latest compatible version. Followings are version details:

• Affected version(s): < 2.1.0
• Patched version(s): 2.1.0
