+  title: HTTP Request Smuggling in ruby webrick
+  date: 2024-09-22
+  description: |
+    An issue was discovered in the WEBrick toolkit through 1.8.1 for Ruby.
+    It allows HTTP request smuggling by providing both a Content-Length
+    header and a Transfer-Encoding header, e.g.,
+    "GET /admin HTTP/1.1\r\n" inside of a "POST /user HTTP/1.1\r\n"
+    request.
+
+    NOTE: the supplier''s position is "Webrick should not be used in production."
+  cvss_v3: 7.5
+  notes: Never patched
