Prior to version 4.12.4, when using serveStatic together with route-based middleware protections (e.g. app.use('/admin/*', ...)), inconsistent URL decoding allowed protected static resources to be accessed without authorization. The router used decodeURI, while serveStatic used decodeURIComponent. This mismatch allowed paths containing encoded slashes (%2F) to bypass middleware protections while still resolving to the intended filesystem path. This issue has been patched in version 4.12.4."},{"lang":"es","value":"Hono es un framework de aplicación web que proporciona soporte para cualquier tiempo de ejecución de JavaScript. Antes de la versión 4.12.4, cuando se usaba serveStatic junto con protecciones de middleware basadas en rutas (p. ej., app.use('/admin/*', ...)), una decodificación inconsistente de URL permitía que se accediera a recursos estáticos protegidos sin autorización. El router usaba decodeURI, mientras que serveStatic usaba decodeURIComponent.
