CVE-2024-55662Public exploitNetwork attack vector

Authenticated code execution via unrestricted extension descriptions

Published Dec 12, 2024 · Updated Dec 13, 2024

Static code injection in affected XWiki Platform releases allows remote authenticated users to execute arbitrary server-side code. ExtensionCode.ExtensionSheet rendered the stored ExtensionClass description directly, so embedded Groovy macros ran without a restricted transformation context. A normal account without script or programming rights can add the object when the optional Extension Repository Application is installed, gaining programming-right code execution.
