XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In affected versions it's possible to execute a content with the right of any user via a crafted URL. A user must have `programming` privileges in order to exploit this vulnerability. This issue has been patched in XWiki 14.10.7 and 15.2RC1. Users are advised to upgrade. There are no known workarounds for for this vulnerability.

GHSA-hgpw-6p4h-j6h5 — XWiki Platform vulnerable to remote code execution via the edit action because it lacks CSRF token

Affected: Maven: org.xwiki.platform:xwiki-platform-oldcore

### Impact

In XWiki Platform, it's possible to execute content with the right of any user if you can make this user follow a crafted URL. This is possible because edit action sets and thereby executes the page content without checking for a cross-site request forgert (CSRF) token.

To reproduce: Get a user with programming rights to visit the URL `<xwiki-host>/xwiki/bin/edit/Main/?content=%7B%7Bgroovy%7D%7Dprintln%28%22Hello+from+Groovy%21%22%29%7B%7B%2Fgroovy%7D%7D&xpage=view`, where `<xwiki-host>` is the URL of your XWiki installation. This can be done by embedding an image with this URL.

The text "Hello from Groovy!" is displayed in the page content, showing that the Groovy macro has been executed.

### Patches

This has been patched in XWiki 14.10.7 and 15.2-RC-1.

### Workarounds There are no known workarounds for it.
