CVE-2025-30148

Silverstripe Framework has a XSS vulnerability in HTML editor

Published Apr 10, 2025 CVSS 3.1 · 5.4 Medium EPSS < 1% KEV · Not listed
Description
Silverstripe Framework is a PHP framework which powers the Silverstripe CMS. Prior to 5.3.23, bad actor with access to edit content in the CMS could send a specifically crafted encoded payload to the server, which could be used to inject a JavaScript payload on the front end of the site. The payload would be sanitized on the client-side, but server-side sanitization doesn't catch it. The server-side sanitization logic has been updated to sanitize against this attack. This vulnerability is fixed in 5.3.23.
