Published: 4/10/2025Modified: 4/10/2025
Also known as:GHSA-rhx4-hvx9-j387
Description
### Impact A 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 sanitised on the client-side, but server-side sanitisation doesn't catch it. The server-side sanitisation logic has been updated to sanitise against this attack. ### Reported by James Nicoll from Fujitsu Cyber ### References - https://www.silverstripe.org/download/security-releases/cve-2025-30148
