CVE-2023-29204Public exploitNetwork attack vector

Open redirect via incomplete absolute-URL recognition

Published Apr 15, 2023 · Updated Feb 6, 2025

Open redirect in XWiki Platform allows remote attackers to send users to an external site via crafted xredirect values on login or logout. XWikiServletResponse.sendRedirect recognizes only scheme strings containing :// as absolute, so //host and http:/host forms bypass the trusted-domain check. Exploitation is unauthenticated but requires a user to follow a crafted internal-looking link, enabling phishing without reported server data modification or service interruption.
