NVD Description

Note: Versions mentioned in the description apply only to the upstream ghost package and not the ghost package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.12.25, with credentials: true and no explicit origin (the default wildcard), the CORS Middleware reflects the request's Origin and sends Access-Control-Allow-Credentials: true. Any site can then make credentialed cross-origin requests and read the responses, exposing cookie-authenticated endpoints to arbitrary origins. This vulnerability is fixed in 4.12.25.
