Severity ?
5.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N
Summary
Leading white space bypasses protocol validation
Details

Impact

Whitespace characters are not removed from the beginning of the protocol, so URLs are not parsed properly and protocol validation mechanisms may fail.

Patches

Patched in 1.19.9

Workarounds

Remove leading whitespace from values before passing them to URI.parse (e.g. via .href(value) or new URI(value)), e.g. by using

js function remove_whitespace(url){ const whitespace = /^[\x00-\x20\u00a0\u1680\u2000-\u200a\u2028\u2029\u202f\u205f\u3000\ufeff]+/; url = url.replace(whitespace, '') return url }
