Authenticated code execution via unchecked servlet request access

Published Apr 8, 2026 · Updated Apr 8, 2026

Missing authorization in XWiki Platform before 17.4.8 and 17.10.1 allows remote authenticated users to execute arbitrary server-side code. ScriptXWikiServletRequest.getRequest returns the underlying servlet request, which performs no security checks, to Velocity scripts without requiring programming right. An account with script right can escape Velocity sandbox restrictions, run arbitrary Python scripts, and obtain full access to instance data and operations.
