Cascade Set CORS to Allow All Origins

CORS configuration is too permissive after Cascade set it to allow all origins ('*'). This is a security vulnerability that allows any website to make requests to your API, potentially accessing user data through browser-based attacks like CSRF.

Cascade likely used wildcard to 'fix' CORS issues without understanding security implications.

Error Messages You Might See

CORS policy: Access-Control-Allow-Origin: * CORS security configuration too permissive Wildcard CORS allows all origins
CORS policy: Access-Control-Allow-Origin: *CORS security configuration too permissiveWildcard CORS allows all origins

Common Causes

  1. Cascade added .allowedOrigins("*") to permit all domains
  2. CORS configuration allows all HTTP methods and headers
  3. allowCredentials=true with wildcard origins (security violation)

How to Fix It

Restrict CORS to specific allowed domains only. Specify exact origins: allowedOrigins("https://example.com", "https://app.example.com"). Be explicit about allowed methods (GET, POST) and headers. Never combine allowCredentials(true) with wildcard. Review CORS policy in WebSecurityConfig.

Frequently Asked Questions

What's wrong with CORS wildcard?

Wildcard (*) allows any website to make requests. Combined with credentials, enables CSRF attacks.

How do I restrict CORS safely?
