CVE-2023-27489

描述

### Impact Kiwi TCMS accepts SVG files uploaded by users which could potentially contain JavaScript code. If SVG images are viewed directly, i.e. not rendered in an HTML page, this JavaScript code could execute. ### Patches This vulnerability has been fixed by configuring Kiwi TCMS to serve with the Content-Security-Policy HTTP header which blocks inline JavaScript in all modern browsers. ### Workarounds Configure Content-Security-Policy header, see [commit 6617cee0](https://github.com/kiwitcms/Kiwi/commit/6617cee0fb70cc394b7be6bbc86ef84e6e9de077). ### References You can visit https://digi.ninja/blog/svg_xss.php for more technical details.
