+
+## 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                                         |

+| `%00`             | `NULL` (null character) | `entryPoints.<name>.`<br/>`.http.encodedCharacters`<br/>`.allowEncodedNullCharacter` |

+# 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"
+    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.encodedCharacters]
+    allowEncodedSlash = false
+    allowEncodedBackSlash = false
+    allowEncodedNullCharacter = false
+    allowEncodedSemicolon = false
+    allowEncodedPercent = false
+    allowEncodedQuestionMark = false
+    allowEncodedHash = false
+```
+
+```bash tab="CLI"
+--entryPoints.websecure.address=:443
+--entryPoints.websecure.encodedCharacters.allowEncodedSlash=false
+--entryPoints.websecure.encodedCharacters.allowEncodedBackSlash=false
+--entryPoints.websecure.encodedCharacters.allowEncodedNullCharacter=false
