Security

NB: If your application relies on cross-origin or same-site (same subdomain) requests do not blindly push this version to production

The CSRF middleware now supports the Sec-Fetch-Site header as a modern, defense-in-depth approach to CSRF
protection, implementing the OWASP-recommended Fetch Metadata API alongside the traditional token-based mechanism.

How it works:

Modern browsers automatically send the Sec-Fetch-Site header with all requests, indicating the relationship
between the request origin and the target. The middleware uses this to make security decisions:

• same-origin or none: Requests are allowed (exact origin match or direct user navigation)
• same-site: Falls back to token validation (e.g., subdomain to main domain)
• cross-site: Blocked by default with 403 error for unsafe methods (POST, PUT, DELETE, PATCH)

For browsers that don't send this header (older browsers), the middleware seamlessly falls back to
traditional token-based CSRF protection.

New Configuration Options:

• TrustedOrigins []string: Allowlist specific origins for cross-site requests (useful for OAuth callbacks, webhooks)
• AllowSecFetchSiteFunc func(echo.Context) (bool, error): Custom logic for same-site/cross-site request validation

Example:

e.Use(middleware.CSRFWithConfig(middleware.CSRFConfig{
    // Allow OAuth callbacks from trusted provider
    TrustedOrigins: []string{"https://oauth-provider.com"},

    // Custom validation for same-site requests
    AllowSecFetchSiteFunc: func(c echo.Context) (bool, error) {
        // Your custom authorization logic here
        return validateCustomAuth(c), nil
        // return true, err  // blocks request with error
        // return true, nil  // allows CSRF request through
        // return false, nil // falls back to legacy token logic
    },
}))

Type-Safe Generic Parameter Binding

• Added generic functions for type-safe parameter extraction and context access by @​aldas in #​2856

  Echo now provides generic functions for extracting path, query, and form parameters with automatic type conversion,
  eliminating manual string parsing and type assertions.

  New Functions:

  • Path parameters: PathParam[T], PathParamOr[T]
  • Query parameters: QueryParam[T], QueryParamOr[T], QueryParams[T], QueryParamsOr[T]
  • Form values: FormParam[T], FormParamOr[T], FormParams[T], FormParamsOr[T]
  • Context store: ContextGet[T], ContextGetOr[T]

  Supported Types:
  Primitives (bool, string, int/uint variants, float32/float64), time.Duration, time.Time
  (with custom layouts and Unix timestamp support), and custom types implementing BindUnmarshaler,
  TextUnmarshaler, or JSONUnmarshaler.

  Example:

  // Before: Manual parsing
  idStr := c.Param("id")
  id, err := strconv.Atoi(idStr)
  
  // After: Type-safe with automatic parsing
  id, err := echo.PathParam[int](c, "id")
  
  // With default values
  page, err := echo.QueryParamOr[int](c, "page", 1)
  limit, err := echo.QueryParamOr[int](c, "limit", 20)
  
  // Type-safe context access (no more panics from type assertions)
  user, err := echo.ContextGet[*User](c, "user")

DEPRECATION NOTICE Timeout Middleware Deprecated - Use ContextTimeout Instead

The middleware.Timeout middleware has been deprecated due to fundamental architectural issues that cause
data races. Use middleware.ContextTimeout or middleware.ContextTimeoutWithConfig instead.

Why is this being deprecated?

The Timeout middleware manipulates response writers across goroutine boundaries, which causes data races that
cannot be reliably fixed without a complete architectural redesign. The middleware:

• Swaps the response writer using http.TimeoutHandler
• Must be the first middleware in the chain (fragile constraint)
• Can cause races with other middleware (Logger, metrics, custom middleware)
• Has been the source of multiple race condition fixes over the years

What should you use instead?

The ContextTimeout middleware (available since v4.12.0) provides timeout functionality using Go's standard
context mechanism. It is:

• Race-free by design
• Can be placed anywhere in the middleware chain
• Simpler and more maintainable
• Compatible with all other middleware

Migration Guide:

// Before (deprecated):
e.Use(middleware.Timeout())

// After (recommended):
e.Use(middleware.ContextTimeout(30 * time.Second))

Important Behavioral Differences:

1. Handler cooperation required: With ContextTimeout, your handlers must check context.Done() for cooperative
   cancellation. The old Timeout middleware would send a 503 response regardless of handler cooperation, but had
   data race issues.

2. Error handling: ContextTimeout returns errors through the standard error handling flow. Handlers that receive
   context.DeadlineExceeded should handle it appropriately:

e.GET("/long-task", func(c echo.Context) error {
    ctx := c.Request().Context()

    // Example: database query with context
    result, err := db.QueryContext(ctx, "SELECT * FROM large_table")
    if err != nil {
        if errors.Is(err, context.DeadlineExceeded) {
            // Handle timeout
            return echo.NewHTTPError(http.StatusServiceUnavailable, "Request timeout")
        }
        return err
    }

    return c.JSON(http.StatusOK, result)
})

3. Background tasks: For long-running background tasks, use goroutines with context:

e.GET("/async-task", func(c echo.Context) error {
    ctx := c.Request().Context()

    resultCh := make(chan Result, 1)
    errCh := make(chan error, 1)

    go func() {
        result, err := performLongTask(ctx)
        if err != nil {
            errCh <- err
            return
        }
        resultCh <- result
    }()

    select {
    case result := <-resultCh:
        return c.JSON(http.StatusOK, result)
    case err := <-errCh:
        return err
    case <-ctx.Done():
        return echo.NewHTTPError(http.StatusServiceUnavailable, "Request timeout")
    }
})

v4.14.0

Compare Source

middleware.Logger has been deprecated. For request logging, use middleware.RequestLogger or
middleware.RequestLoggerWithConfig.

middleware.RequestLogger replaces middleware.Logger, offering comparable configuration while relying on the
Go standard library’s new slog logger.

The previous default output format was JSON. The new default follows the standard slog logger settings.
To continue emitting request logs in JSON, configure slog accordingly:

slog.SetDefault(slog.New(slog.NewJSONHandler(os.Stdout, nil)))
e.Use(middleware.RequestLogger())

BREAKING CHANGE JWT Middleware Removed from Core use labstack/echo-jwt instead

The JWT middleware has been removed from Echo core due to another security vulnerability, CVE-2024-51744. For more details, refer to issue #​2699. A drop-in replacement is available in the labstack/echo-jwt repository.

Important: Direct assignments like token := c.Get("user").(*jwt.Token) will now cause a panic due to an invalid cast. Update your code accordingly. Replace the current imports from "github.com/golang-jwt/jwt" in your handlers to the new middleware version using "github.com/golang-jwt/jwt/v5".

Background:

The version of golang-jwt/jwt (v3.2.2) previously used in Echo core has been in an unmaintained state for some time. This is not the first vulnerability affecting this library; earlier issues were addressed in PR #​1946.
JWT middleware was marked as deprecated in Echo core as of v4.10.0 on 2022-12-27. If you did not notice that, consider leveraging tools like Staticcheck to catch such deprecations earlier in you dev/CI flow. For bonus points - check out gosec.

We sincerely apologize for any inconvenience caused by this change. While we strive to maintain backward compatibility within Echo core, recurring security issues with third-party dependencies have forced this decision.

• optimization: struct alignment by @​behnambm in #​2636
