CVE-2022-24723
Leading white space bypasses protocol validation
描述
### 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](https://github.com/medialize/URI.js/)
