WPMobile.App <= 11.56 - Open Redirect

id: CVE-2024-13888

info:
  name: WPMobile.App <= 11.56 - Open Redirect
  author: s4e-io
  severity: high
  description: |
    The WPMobile.App plugin for WordPress is vulnerable to Open Redirect in all versions up to, and including, 11.56. This is due to insufficient validation on the redirect URL supplied via the 'redirect' parameter. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites if they can successfully trick them into performing an action.
  impact: |
    Unauthenticated attackers can redirect users to malicious phishing sites or credential harvesting pages via the redirect parameter.
  remediation: |
    Update WPMobile.App plugin to a version newer than 11.56.
