CVE-2023-29202Network attack vector

Cross-site scripting via unsanitized RSS content

Published Apr 15, 2023 · Updated Feb 6, 2025

Cross-site scripting in XWiki Platform before 14.6 RC1 allows remote authenticated users to execute JavaScript via malicious RSS feed content. The RssMacro rendered feed descriptions as raw HTML when content=true, without cleaning untrusted markup, allowing script injection. Exploitation requires a user with programming rights to place or invoke the macro and a victim to view the page; resulting actions run with the victim's privileges and can affect wiki data and services.
