DescriptionCVE.org

Grav CMS 1.7.49 is vulnerable to Cross Site Scripting (XSS). The page editor allows authenticated users to edit page content via a Markdown editor. The editor fails to properly sanitize <script> tags, allowing stored XSS payloads to execute when pages are viewed in the admin interface.

Analysis

Technical ContextAI

Cross-site scripting (XSS) allows injection of client-side scripts into web pages viewed by other users due to insufficient output encoding.

RemediationAI

Encode all user-supplied output contextually (HTML, JS, URL). Implement Content Security Policy (CSP) headers. Use HTTPOnly and Secure cookie flags.
