CVE-2023-45136Public exploitNetwork attack vector

Reflected XSS via unescaped template-provider errors

Published Oct 25, 2023 · Updated Sep 10, 2024

Reflected XSS in XWiki Platform allows remote attackers to execute actions as a user who opens a crafted page-creation link. The createinline.vm template renders template-provider restriction errors with attacker-controlled document-name data without XML escaping. Exposure requires the disabled-by-default name-validation setting; the user's rights bound the result, from wiki reads and writes to code execution.
