CVE-2025-66468Network attack vector

Stored XSS via unsanitized CMS content

Published Dec 2, 2025 · Updated Dec 2, 2025

Stored XSS in Aimeos GrapesJS CMS allows remote authenticated users to execute JavaScript in other users' browsers via saved content. The fromArray method in src/Admin/JQAdm/Cms/Content/Standard.php stores text.content without HTML sanitization, allowing script-bearing markup to persist. Exploitation requires malicious editor privileges, a victim to render the stored content, and the standard CSP to be disabled; production mode enables that CSP by default.
