CVE-2022-2217Public exploitNetwork attack vector

Script execution via misparsed JavaScript URLs

Published Jun 27, 2022 · Updated Aug 3, 2024

Cross-site scripting in parse-url before 7.0.0 allows remote attackers to execute browser-side script through a crafted URL. The parseUrl function fails to canonicalize a control-character-obfuscated JavaScript scheme, so its returned href can pass a consumer's scheme check unchanged. Exploitation requires a consuming web application to insert that href into HTML and a user to follow or otherwise interact with the resulting link.
