Description

URI.js is a Javascript URL mutation library. Before version 1.19.9, whitespace characters are not removed from the beginning of the protocol, so URLs are not parsed properly. This issue has been patched in version 1.19.9. Removing leading whitespace from values before passing them to URI.parse can be used as a workaround.

Affected products

• medialize/uri.js: before 1.19.9 — fixed in 1.19.9

How to fix

Upgrade to a fixed version: medialize/uri.js 1.19.9. Check the vendor advisory for mitigations.
