Hono is a Web application framework that provides support for any JavaScript runtime. Prior to version 4.11.7, Serve static Middleware for the Cloudflare Workers adapter contains an information disclosure vulnerability that may allow attackers to read arbitrary keys from the Workers environment. Improper validation of user-controlled paths can result in unintended access to internal asset keys. Version 4.11.7 contains a patch for the issue.
