CVE-2026-54290 Details
Description
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.
A vulnerability in the Hono web application framework, affecting versions prior to 4.12.25, allows for credentialed cross-origin requests to be made to cookie-authenticated endpoints. This issue arises when the CORS middleware is configured to reflect the request's Origin without an explicit origin set, defaulting to a wildcard. As a result, any site can access sensitive cookie-authenticated data and perform state-changing actions on behalf of the user.
Users can upgrade to Hono version 4.12.25 or later to address this vulnerability.
