In short

A vulnerability in XWiki's Flamingo theme allows any user with basic viewing permissions to run malicious code (Groovy, Python, or Velocity) that can take over the entire XWiki installation. This happens because the documentTree macro doesn't properly clean up user input before processing it.

Technical detail

The documentTree macro in FlamingoThemesCode.WebHome fails to properly escape parameters, allowing code injection attacks. An authenticated user with view rights can inject arbitrary Groovy, Python, or Velocity code through macro parameters, leading to remote code execution with full XWiki installation access. Attack requires only view-level permissions on default-installed documents.
