Name of the Vulnerable Software and Affected Versions: Decap CMS versions through 3.8.3

Description: A Cross Site Scripting (XSS) vulnerability exists in Decap CMS. Input fields, including body, tags, title, and description, are not properly sanitized before being rendered in the content preview pane. This allows an attacker to inject arbitrary JavaScript that executes when a user views the preview panel. The vulnerability affects multiple input vectors and does not require user interaction beyond viewing the affected content.

Recommendations: Update Decap CMS to a version later than 3.8.3.
