Vulnerability details

The vulnerability allows a remote user to perform server-side request forgery and access internal or cloud-hosted resources.

The vulnerability exists due to improper control of server-side request targets in the wiki PDF export in public/main/wiki/wiki.inc.php when rendering user-controlled wiki HTML to PDF. A remote user can embed external URLs in <img src> attributes or CSS url() values to perform server-side request forgery and access internal or cloud-hosted resources.
