CVE-2023-35161Public exploitNetwork attack vector

Reflected XSS via unsanitized xredirect URL

Published Jun 23, 2023 · Updated Nov 27, 2024

Reflected XSS in affected XWiki Platform releases allows remote attackers to execute script through a crafted xredirect URL. DeleteApplication.xml assigns request.xredirect directly to a cancel-link URL without sanitizing its value for an HTML href attribute. Exploitation requires a user to open the forged URL; the script runs under the XWiki origin and can perform actions with that user's rights.
