+title: ReDoS Vulnerability in Rack::Multipart handle_mime_head
+date: 2025-06-05
+description: |
+  ### Summary
+
+  There is a denial of service vulnerability in the
+  Content-Disposition parsing component of Rack. This is very
+  similar to the previous security issue CVE-2022-44571.
+
+  ### Details
+
+  Carefully crafted input can cause Content-Disposition header
+  parsing in Rack to take an unexpected amount of time, possibly
+  resulting in a denial of service attack vector. This header is
+  used typically used in multipart parsing. Any applications that
+  parse multipart posts using Rack (virtually all Rails applications)
+  are impacted.
