Gradio - Open Redirect

id: CVE-2024-4940

info:
  name: Gradio - Open Redirect
  author: DhiyaneshDK
  severity: medium
  description: |
    An open redirect vulnerability exists in the gradio-app/gradio, affecting the latest version. The vulnerability allows an attacker to redirect users to arbitrary websites, which can be exploited for phishing attacks, Cross-site Scripting (XSS), Server-Side Request Forgery (SSRF), amongst others. This issue is due to improper validation of user-supplied input in the handling of URLs. Attackers can exploit this vulnerability by crafting a malicious URL that, when processed by the application, redirects the user to an attacker-controlled web page.
  impact: |
    Attackers can redirect users to malicious websites via open redirect, potentially enabling phishing attacks.
  remediation: |
    Update Gradio to a version that patches the open redirect vulnerability.
