| 説明 | Vulnerability Description
A GET-based Open Redirect was identified in the logout functionality of Freshwork Product v1.2.3. The application’s logout endpoint accepts a post_logout_redirect_uri parameter from the query string and uses it directly to construct the destination URL after logout, without sufficient validation or sanitization.
This allows an attacker to craft a malicious link that, when clicked, logs out the user and then redirects them to an attacker-controlled site. Such behavior can be abused for phishing campaigns, session termination attacks, or to trick users into trusting a malicious site.
Steps to reproduce:
1. Make a GET request to below URL and define any attacker controlled domain in the post_logout_redirect_uri parameter, result will be redirected to the specified domain.
