WordPress SEO Tools Plugin 4.0.7 - Cross-Site Scripting

id: CVE-2024-13853

info:
  name: WordPress SEO Tools Plugin 4.0.7 - Cross-Site Scripting
  author: ritikchaddha
  severity: medium
  description: |
    The SEO Tools WordPress plugin through version 4.0.7 contains a reflected cross-site scripting vulnerability. The plugin does not properly sanitize and escape the 'src' parameter in the rssread.php file before outputting it back in the page, which could allow attackers to execute arbitrary JavaScript code in a victim's browser.
  impact: |
    Unauthenticated attackers can execute arbitrary JavaScript in a victim's browser via the src parameter, potentially stealing cookies or credentials.
  remediation: |
    Update SEO Tools plugin to a version newer than 4.0.7.
