+  title: Escape Sequence Injection vulnerability in Rack lead to Possible Log Injection
+  date: 2025-03-04
+  description: |
+    ## Summary
+
+    `Rack::Sendfile` can be exploited by crafting input that
+    includes newline characters to manipulate log entries.
+
+    ## Details
+
+    The `Rack::Sendfile` middleware logs unsanitized header values from
+    the `X-Sendfile-Type` header. An attacker can exploit this by
+    injecting escape sequences (such as newline characters) into the
+    header, resulting in log injection.
+
+    ## Impact
+
+    This vulnerability can distort log files, obscure
+    attack traces, and complicate security auditing.
+
+    ## Mitigation
+
+    - Update to the latest version of Rack, or
+    - Remove usage of `Rack::Sendfile`.
