 In `v2.11.14`, the `X-Forwarded-Prefix` header is now handled like the other `X-Forwarded-*` headers: Traefik removes it when it's sent from an untrusted source.

+### Request Path Sanitization
+
+Since `v2.11.23`, the incoming request path is now cleaned before being used to match the router rules and sent to the backends.
+Any `/../`, `/./` or duplicate slash segments in the request path is interpreted and/or collapsed.
+
+If you want to disable this behavior, you can set the [`sanitizePath` option](../routing/entrypoints.md#sanitizepath) to `false` in the entryPoint HTTP configuration.
+This can be useful when dealing with legacy clients that are not url-encoding data in the request path.
+For example, as base64 uses the “/” character internally,
+if it's not url encoded,
+it can lead to unsafe routing when the `sanitizePath` option is set to `false`.
+
+!!! warning "Security"
+
+    Setting the `sanitizePath` option to `false` is not safe.
+    Ensure every request is properly url encoded instead.
