## Description

Pro Macros provides XWiki rendering macros. Missing escaping in the Viewpdf macro allows any user with view right on the `CKEditor.HTMLConverter` page or edit or comment right on any page to perform remote code execution. Other macros like Viewppt are vulnerable to the same kind of attack. This vulnerability is fixed in 1.10.1.

## What to do

- Check your stack: if you ship or depend on xwikisas xwiki-pro-macros, upgrade to a fixed version (1.10.1) per the references below.
