+
+## v2.11.25
+
+### Request Path Normalization
+
+Since `v2.11.25`, the request path is now normalized by decoding unreserved characters in the request path,
+and also uppercasing the percent-encoded characters.
+This follows [RFC 3986 percent-encoding normalization](https://datatracker.ietf.org/doc/html/rfc3986#section-6.2.2.2),
+and [RFC 3986 case normalization](https://datatracker.ietf.org/doc/html/rfc3986#section-6.2.2.1).
+
+The normalization happens before the request path is sanitized,
+and cannot be disabled.
+This notably helps with encoded dots characters (which are unreserved characters) to be sanitized properly.
+
+### Routing Path
+
+Since `v2.11.25`, the reserved characters [(as per RFC 3986)](https://datatracker.ietf.org/doc/html/rfc3986#section-2.2) are kept encoded in the request path when matching the router rules.
+Those characters, when decoded, change the meaning of the request path for routing purposes,
+and Traefik now keeps them encoded to avoid any ambiguity.
+
+### Request Path Matching Examples
+
+| Request Path      | Router Rule            | Traefik v2.11.24 | Traefik v2.11.25 |
+|-------------------|------------------------|------------------|------------------|
+| `/foo%2Fbar`      | PathPrefix(`/foo/bar`) | Match            | No match         |
+| `/foo/../bar`     | PathPrefix(`/foo`)     | No match         | No match         |
+| `/foo/../bar`     | PathPrefix(`/bar`)     | Match            | Match            |
+| `/foo/%2E%2E/bar` | PathPrefix(`/foo`)     | Match            | No match         |
+| `/foo/%2E%2E/bar` | PathPrefix(`/bar`)     | No match         | Match            |
+
+## v2.11.28
+
+### MultiPath TCP
+
+Since `v2.11.28`, the MultiPath TCP support introduced with `v2.11.26` has been removed.
+It appears that enabling MPTCP on some platforms can cause Traefik to stop with the following error logs message:
+
+- `set tcp X.X.X.X:X->X.X.X.X:X: setsockopt: operation not supported`
+
+However, it can be re-enabled by setting the `multipathtcp` variable in the GODEBUG environment variable, see the related [go documentation](https://go.dev/doc/godebug#go-124).
+
+## v2.11.32
+
+### Encoded Characters in Request Path
+
+Since `v2.11.32`, for security reasons Traefik now rejects requests with a path containing a specific set of encoded characters by default.
+When such a request is received, Traefik responds with a `400 Bad Request` status code.
+Here is the list of the encoded characters that are rejected by default, along with the corresponding configuration option to allow them:
+
+| Encoded Character | Character               | Config option to allow the encoded character                                         |

+| `%5c` or `%5C`    | `\` (backslash)         | `entryPoints.<name>.`<br/>`.http.encodedCharacters`<br/>`.allowEncodedBackSlash`     |
+| `%00`             | `NULL` (null character) | `entryPoints.<name>.`<br/>`.http.encodedCharacters`<br/>`.allowEncodedNullCharacter` |
+| `%3b` or `%3B`    | `;` (semicolon)         | `entryPoints.<name>.`<br/>`.http.encodedCharacters`<br/>`.allowEncodedSemicolon`     |
+| `%25`             | `%` (percent)           | `entryPoints.<name>.`<br/>`.http.encodedCharacters`<br/>`.allowEncodedPercent`       |
+| `%3f` or `%3F`    | `?` (question mark)     | `entryPoints.<name>.`<br/>`.http.encodedCharacters`<br/>`.allowEncodedQuestionMark`  |
+| `%23`             | `#` (hash)              | `entryPoints.<name>.`<br/>`.http.encodedCharacters`<br/>`.allowEncodedHash`          |
+
+Note: This check is not done against query parameters,
+but only against the request path as defined in [RFC3986 section-3](https://datatracker.ietf.org/doc/html/rfc3986#section-3).
+
+Please check out the entrypoint [encodedCharacters option](../routing/entrypoints.md#encoded-characters) documentation for more details.

+# Request Path
+
+Protecting Against Path-Based Attacks Through Sanitization and Filtering
+{: .subtitle }
+
+Traefik implements multiple layers of security when processing incoming request paths.
+This includes path sanitization to normalize potentially dangerous sequences and encoded character filtering to prevent attack vectors that use URL encoding.
+Understanding how Traefik handles request paths is crucial for maintaining a secure routing infrastructure.
+
+## How Traefik Processes Request Paths
+
+When Traefik receives an HTTP request, it processes the request path through several security-focused stages:
+
+### 1. Encoded Character Filtering
+
+Traefik inspects the path for potentially dangerous encoded characters and rejects requests containing them unless explicitly allowed.
+
+Here is the list of the encoded characters that are rejected by default:
+
+| Encoded Character | Character               |
+|-------------------|-------------------------|
+| `%2f` or `%2F`    | `/` (slash)             |
+| `%5c` or `%5C`    | `\` (backslash)         |
+| `%00`             | `NULL` (null character) |
+| `%3b` or `%3B`    | `;` (semicolon)         |
+| `%25`             | `%` (percent)           |
+| `%3f` or `%3F`    | `?` (question mark)     |
+| `%23`             | `#` (hash)              |
+
+### 2. Path Normalization
+
+Traefik normalizes the request path by decoding the unreserved percent-encoded characters,
+as they are equivalent to their non-encoded form (according to [rfc3986#section-2.3](https://datatracker.ietf.org/doc/html/rfc3986#section-2.3)),
+and capitalizing the percent-encoded characters (according to [rfc3986#section-6.2.2.1](https://datatracker.ietf.org/doc/html/rfc3986#section-6.2.2.1)).
+
+### 3. Path Sanitization
+
+Traefik sanitizes request paths to prevent common attack vectors,
+by removing the `..`, `.` and duplicate slash segments from the URL (according to [rfc3986#section-6.2.2.3](https://datatracker.ietf.org/doc/html/rfc3986#section-6.2.2.3)).
+
+## Path Security Configuration
+
+Traefik provides two main mechanisms for path security that work together to protect your applications.
+
+### Path Sanitization
+
+Path sanitization is enabled by default and helps prevent directory traversal attacks by normalizing request paths.
+Configure it in the [EntryPoints](../routing/entrypoints.md#sanitizepath) HTTP section:
+
+```yaml tab="File (YAML)"
+entryPoints:
+  websecure:
+    address: ":443"
+    http:
+      sanitizePath: true  # Default: true (recommended)
+```
+
+```toml tab="File (TOML)"
+[entryPoints.websecure]
+  address = ":443"
+
+  [entryPoints.websecure.http]
+    sanitizePath = true
+```
+
+```bash tab="CLI"
+--entryPoints.websecure.address=:443
+--entryPoints.websecure.http.sanitizePath=true
+```
+
+**Sanitization behavior:**
+
+- `./foo/bar` → `/foo/bar` (removes relative current directory)
+- `/foo/../bar` → `/bar` (resolves parent directory traversal)
+- `/foo/bar//` → `/foo/bar/` (removes duplicate slashes)
+- `/./foo/../bar//` → `/bar/` (combines all normalizations)
+
+### Encoded Character Filtering
+
+Encoded character filtering provides an additional security layer by rejecting potentially dangerous URL-encoded characters.
+Configure it in the [EntryPoints](../routing/entrypoints.md#encoded-characters) HTTP section.
+
+This filtering occurs before path sanitization and catches attack attempts that use encoding to bypass other security controls.
+
+All encoded character filtering is enabled by default (`false` means encoded characters are rejected), providing maximum security:
+
+```yaml tab="File (YAML)"
+entryPoints:
+  websecure:
+    address: ":443"
+    http:
+      encodedCharacters:
+        allowEncodedSlash: false          # %2F - Default: false (RECOMMENDED)
+        allowEncodedBackSlash: false      # %5C - Default: false (RECOMMENDED)
+        allowEncodedNullCharacter: false  # %00 - Default: false (RECOMMENDED)
+        allowEncodedSemicolon: false      # %3B - Default: false (RECOMMENDED)
+        allowEncodedPercent: false        # %25 - Default: false (RECOMMENDED)
+        allowEncodedQuestionMark: false   # %3F - Default: false (RECOMMENDED)
+        allowEncodedHash: false           # %23 - Default: false (RECOMMENDED)
+```
+
+```toml tab="File (TOML)"
+[entryPoints.websecure]
+  address = ":443"
+
+  [entryPoints.websecure.http.encodedCharacters]
+    allowEncodedSlash = false
+    allowEncodedBackSlash = false
+    allowEncodedNullCharacter = false
+    allowEncodedSemicolon = false
+    allowEncodedPercent = false
+    allowEncodedQuestionMark = false
+    allowEncodedHash = false
+```
+

+
+# TLS Certificates in Multi‑Tenant Kubernetes
+
+In a shared cluster, different teams can create `Ingress` or `IngressRoute` objects that Traefik consumes.
+
+Traefik does not support multi-tenancy when using the Kubernetes `Ingress` or `IngressRoute` specifications due to the way TLS certificate management is handled.
+
+At the core of this limitation is the TLS Store, which holds all the TLS certificates used by Traefik. 
+As this Store is global in Traefik, it is shared across all namespaces, meaning any `Ingress` or `IngressRoute` in the cluster can potentially reference or affect TLS configurations intended for other tenants.
+
+This lack of isolation poses a risk in multi-tenant environments where different teams or applications require strict boundaries between resources, especially around sensitive data like TLS certificates.
+
+In contrast, the [Kubernetes Gateway API](../providers/kubernetes-gateway.md) provides better primitives for secure multi-tenancy. 
+Specifically, the `Listener` resource in the Gateway API allows administrators to explicitly define which Route resources (e.g., `HTTPRoute`) are permitted to bind to which domain names or ports. 
+This capability enforces stricter ownership and isolation, making it a safer choice for multi-tenant use cases.
+
+## Recommended setup
+
+When strict boundaries are required between resources and teams, we recommend using one Traefik instance per tenant.
+
+In Kubernetes one way to isolate a tenant is to restrict it to a namespace.
+In that case, the namespace options from the Kubernetes [CRD](../providers/kubernetes-crd.md#namespaces) and [Ingress](../providers/kubernetes-ingress.md#namespaces) providers can be leveraged.  
+
+!!! tip "Dedicate one Traefik instance per tenant using the Helm Chart" 
+
+    ```yaml
+    providers:
+      kubernetesCRD:
+        namespaces:
+          - tenant
+      kubernetesIngress:
+        namespaces:
+          - tenant
