CVE-2022-37429Network attack vector

Stored XSS via whitespace-split JavaScript href

Published Nov 23, 2022 · Updated Apr 25, 2025

Stored XSS in Silverstripe Framework allows remote authenticated users to execute JavaScript in visitors' browsers through crafted links. HTMLEditor accepts a link href in which whitespace splits the javascript scheme, leaving the stored payload executable when rendered. CMS access as a content author and a visitor opening the stored content are required, limiting the consequence to browser-context script execution.
