Description TEJ RATHI 2023-05-19 11:13:43 UTC

An improper handling of RSS titles in inc/parser/xhtml.php, a malicious RSS feed can be used to inject arbitrary HTML elements into the page, resulting in cross-site scripting.

Impact: An attacker can execute arbitrary JavaScript on Dokuwiki origin. Since administrators can install plugins, this could result in remote code execution if the administrator opens a page with crafted content.
