CVE-2023-35158Public exploitNetwork attack vector

Reflected XSS via unsanitized restore redirect

Published Jun 23, 2023 · Updated Nov 27, 2024

Reflected XSS in affected XWiki Platform versions allows remote attackers to run JavaScript in another user's browser via a crafted URL. The restore.vm template places the xredirect request value in a cancel-link href without rejecting script-bearing URL schemes. A victim must open the forged restore page and activate its cancel link; the script then runs in the victim's XWiki origin with that session's access.
