Browser session compromise via unsanitized CKEditor content

Published May 8, 2026 · Updated May 8, 2026

Stored XSS in Brave CMS before commit 6c56603 allows remote authenticated users to execute script in visitors' browsers via page or article content. ArticleController and PageController store CKEditor body fields without sanitization, and Blade templates render the values through unescaped output directives. An author or editor account is required to plant content, and exploitation occurs when a visitor loads the affected page, exposing that visitor's browser session.
