CVE-2023-29508Public exploitNetwork attack vector

Stored XSS via unsanitized Live Data HTML

Published Apr 16, 2023 · Updated Feb 6, 2025

Stored XSS in XWiki Platform 13.10.10, 14.4 through 14.4.6, and 14.9 allows remote authenticated users to execute browser scripts. The Live Data macro's HTML displayer renders attacker-controlled entry values as raw HTML instead of neutralizing script-capable markup. The attacker needs page-editing access without script rights, the page's last content author must hold script rights, and a viewer must render the saved page.
