CVE-2026-39406

CVSS v3.1

5.3

Medium

VectorAV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
Name of the Vulnerable Software and Affected Versions @hono/node-server versions prior to 1.19.13
Description 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 router may not match paths containing repeated slashes, while serveStatic resolves them as normalized paths, leading to a middleware bypass. An attacker can access static files intended to be protected by route-based middleware by using repeated slashes in the request path. This can lead to unauthorized access to sensitive files under the static root.
Recommendations Update @hono/node-server to version 1.19.13 or later.
