[dependabot]

Bumps github.com/labstack/echo/v4 from 4.13.4 to 4.15.0.

Release notes

Sourced from github.com/labstack/echo/v4's releases.

v4.15.0

Security

WARNING: 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
},

}))

PR: labstack/echo#2858

Type-Safe Generic Parameter Binding

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

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