  description: |
    The Instagram Feed WordPress plugin before 1.6 contains a reflected cross-site scripting (XSS) vulnerability due to improper sanitization of user-supplied input, allowing attackers to inject malicious scripts via crafted requests.
  impact: |
    Attackers with administrator privileges can execute malicious Javascript in the context of the site, potentially stealing cookies or hijacking user sessions.
  remediation: |
    Update to version 1.6 or later.
