AI-analyzed exploit summary The repository contains a functional proof-of-concept exploit for CVE-2026-33229, demonstrating an RCE vulnerability in XWiki Platform via Apache Velocity sandbox bypass. The PoC leverages pre-instantiated objects in the Velocity context to execute arbitrary commands without requiring Java Reflection.
Description
XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. Prior to 17.4.8 and 17.10.1, an improperly protected scripting API allows any user with script right to bypass the sandboxing of the Velocity scripting API and execute, e.g., arbitrary Python scripts, allowing full access to the XWiki instance and thereby compromising the confidentiality, integrity and availability of the whole instance. Note that script right already constitutes a high level of access that we don't recommend giving to untrusted users. This vulnerability is fixed in 17.4.8 and 17.10.1.
