CVE-2024-32981 – Cross-site Scripting vulnerability with encoded payload in silverstripe/framework

https://notcve.org/view.php?id=CVE-2024-32981

Silverstripe framework is the PHP framework forming the base for the Silverstripe CMS. In affected versions a bad actor with access to edit content in the CMS could add 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 type of attack in version 5.2.16. All users are advised to upgrade. • https://github.com/silverstripe/silverstripe-framework/commit/b8d20dc9d531550e06fd7da7a0eafa551922e2e1 https://github.com/silverstripe/silverstripe-framework/security/advisories/GHSA-chx7-9x8h-r5mg https://www.silverstripe.org/download/security-releases/cve-2024-32981 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
