@​hono/node-server: serveStatic decodes the request path a second time, leading to bypass of middleware on static paths

CVE-2026-118663 / GHSA-rmxm-3fg6-px4f

More information

Details

Summary

serveStatic decodes the request path a second time after Hono has already decoded it for routing. A crafted request can be routed as one path and served as another, so middleware mounted on a static prefix does not run for a file under that prefix.

Details

Hono decodes the request path once before routing. serveStatic decoded it again before resolving the file. With a malformed percent-encoded sequence, the first decode leaves part of the path encoded, the router matches the encoded form, and the second decode resolves the real directory. The file is still resolved inside the configured root; this is not a traversal outside it.

Impact

An unauthenticated attacker may reach static files without the middleware on their prefix running, for example an authentication check. This affects applications that mount middleware on part of the directory served by serveStatic. Applications that serve only public files are not affected.

Security fixes

serveStatic decodes the request path a second time, leading to bypass of middleware on static paths

Affects: @hono/node-server/serve-static. Fixes serveStatic decoding an already-decoded path, where a crafted request could be routed as one path and served as another, skipping middleware mounted on a static prefix. GHSA-rmxm-3fg6-px4f

serveStatic now rejects request paths that still contain % after decoding. To serve files whose names contain a literal %, set allowPercentInPath: true.

The same fix ships in hono v4.13.11.

v2.1.2
