CVE-2025-47908 Denial of service via malicious preflight requests in github.com/rs/cors

Middleware causes a prohibitive amount of heap allocations when processing malicious preflight requests that include a Access-Control-Request-Headers ACRH header whose value contains many commas. This behavior can be abused by attackers to produce undue load on the middleware/server as an attempt...

CVE-2024-10906

In version 0.6.0 of eosphoros-ai/db-gpt, the uvicorn app created by dbgptserver uses an overly permissive instance of CORSMiddleware which sets the Access-Control-Allow-Origin to for all requests. This configuration makes all endpoints exposed by the server vulnerable to Cross-Site Request Forger...
