Affected packages

• npm urijs: < 1.19.9 → fixed in 1.19.9

Description

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 } ``` References • https://huntr.dev/bounties/82ef23b8-7025-49c9-b5fc-1bb9885788e5/ For more information If you have any questions or comments about this advisory: • Open an issue in medialize/URI.js
