DescriptionGitHub Advisory
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.
AnalysisAI
Hono versions before 4.11.7 contain an information disclosure vulnerability in the static file serving middleware for Cloudflare Workers that allows unauthenticated remote attackers to read sensitive environment keys through path traversal. The lack of proper input validation enables attackers to access internal asset keys that should remain protected. A patch is available in version 4.11.7 and later.
