id: CVE-2025-68602

info:
  name: Accept Donations with PayPal <= 1.5.2 - Open Redirect
  author: Shivam Kamboj
  severity: medium
  description: |
    The Accept Donations with PayPal & Stripe plugin for WordPress is vulnerable to Open Redirect in all versions up to, and including, 1.5.2. This is due to insufficient validation on the redirect url supplied. 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: |
    Attackers can redirect users to malicious sites, facilitating phishing attacks and credential theft.
  remediation: |
    Update to the latest version beyond 1.5.1.
