    @webiny/react-rich-text-renderer vulnerable to insecure rendering of rich text content

    CVE-2023-41167 · GHSA-3x59-vrmc-5mx6

    Affected
    • npm @webiny/react-rich-text-renderer <= 5.37.1
    Fixed in
    5.37.2· Vendor fix available
    Issue
    @webiny/react-rich-text-renderer is a react component to render data coming from Webiny Headless CMS and Webiny Form Builder. The @webiny/react-rich-text-renderer package depends on the editor.js rich text editor to handle rich text content. The CMS stores rich text content from the editor.js into the database. When the @webiny/react-rich-text-renderer is used to render such content, it uses the dangerouslySetInnerHTML prop, without applying HTML sanitization. The issue arises when an actor, who in this context would specifically be a content manager with access to the CMS, inserts a malicious script as part of the user-defined input. This script is then injected and executed within the user's browser when the main page or admin page loads. Am I affected?

If you've already switched to using the new rich…

    Recommended action: Upgrade to 5.37.2 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
