CVE-2026-39406: Improper Limitation of a Pathname to a Restricted Directory

@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. When route-based middleware e.g., /admin/ is used for authorization, the...

Directory Traversal

Overview org.webjars.npm:h3 is a Minimal HTTP framework built for high performance and portability. Affected versions of this package are vulnerable to Directory Traversal via the serveStatic utility. An attacker can access arbitrary files from backend storage by sending specially crafted request...

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...
