CVE-2026-39407

Hono (Web framework) prior to 4.12.12 is affected by a path handling inconsistency in serveStatic: repeated slashes in the request path can bypass route-based middleware (e.g., /admin/*) and expose protected static files. The issue arises because the router may not match paths with // while serve...

CVE-2026-39406 @hono/node-server has a middleware bypass via repeated slashes in serveStatic

@hono/node-server allows running the Hono application on Node.js. Prior to 1.19.13, a path handling inconsistency in serveStatic allows protected static files to be accessed by using repeated slashes // in the request path.

h3: Double Decoding in `serveStatic` Bypasses `resolveDotSegments` Path Traversal Protection via `%252e%252e`

Summary The serveStatic utility in h3 applies a redundant decodeURI call to the request pathname after H3Event has already performed percent-decoding with %25 preservation. This double decoding converts %252e%252e into %2e%2e, which bypasses resolveDotSegments since it checks for literal...
