What it is

🔥 A crafty annotation lets anyone with author rights execute anything they want! This is a serious gap in XWiki that demands your immediate attention! Think of it like a guest book where anyone can add a sticky note with instructions to control the entire event. If no one is checking what gets written, chaos could ensue! An attacker could misuse this flaw to execute arbitrary code under the privileges of the document's author, potentially leading to data breaches or complete system compromise. It’s like giving a guest the master key to your house just because they signed the visitor log – absolutely devastating!

Put simply

Think of it like a guest book where anyone can add a sticky note with instructions to control the entire event. If no one is checking what gets written, chaos could ensue! This vulnerability in XWiki allows unauthorized code execution via document annotations since the content is not executed in a restricted context. Attackers can leverage their author rights to run anything they desire, creating grave security risks.

What to do

An attacker could misuse this flaw to execute arbitrary code under the privileges of the document's author, potentially leading to data breaches or complete system compromise. It’s like giving a guest the master key to your house just because they signed the visitor log – absolutely devastating! Upgrade to XWiki version 13.10.11, 14.4.7, or 14.10 immediately to close this gap. There are no workarounds available, so prompt action is essential! You've got this! Follow these steps, and you’ll have your XWiki secured in no time! 🛡️
