CVE-2024-21650Public exploitNetwork attack vector

Unauthenticated code execution via unescaped registration names

Published Jan 8, 2024 · Updated Jun 17, 2025

Eval injection in XWiki Platform allows remote attackers to execute arbitrary code through the guest user registration flow. The registration success message inserts first-name and last-name request values into XWiki syntax, allowing crafted closing tags to introduce an asynchronous Groovy macro. Guest registration must be enabled, after which submitting the form executes the injected macro with server-side privileges.
