CVE-2025-30148

Name of the Vulnerable Software and Affected Versions: Silverstripe Framework versions prior to 5.3.23

Description: 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 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.

Recommendations: For versions prior to 5.3.23, update to version 5.3.23 to fix the issue.
