Full Changelog: honojs/node-server@v2.1.7...v2.1.8

v2.1.7

Security fixes

This release includes a fix for the following security issue:

serveStatic with allowPercentInPath still allows the double-decode middleware bypass

Affects: serveStatic with allowPercentInPath: true. The fix for GHSA-rmxm-3fg6-px4f rejects a path containing %, but the allowPercentInPath option skipped that check entirely. A malformed percent sequence such as /static/%%36%31dmin/secret.txt was routed as /static/%61dmin/secret.txt, so middleware on /static/admin/* did not run, and serveStatic then decoded %61 to a and served static/admin/secret.txt. The default configuration was already fixed in 2.1.3. GHSA-fj57-4f93-cfw6

serveStatic now accepts the second decode only when its result equals the routed path with %25 replaced by %. File names containing a literal %, requested as %25, are served as before.

---

The same fix ships in hono v4.13.18 (GHSA-74fm-fwc7-3fwp).

v2.1.6

Security fixes

This release includes fixes for the following security issues:

Backslash in the request path is parsed as a path separator, bypassing path-based access control at a reverse proxy

Affects: all requests. The raw request-target was passed to the WHATWG URL parser, which treats a backslash in the path as / and resolves .. segments, so /admin\secret reached the application as /admin/secret. A reverse proxy that forwards the backslash unchanged applied its path-based rules to the original path. GHSA-jpvv-r467-5p4w

A request whose path contains a raw backslash is now rejected with 400 Bad Request, for HTTP/1.1, HTTP/2 and WebSocket upgrades. A percent-encoded backslash (%5C) and a backslash in the query string are still accepted.

WebSocket upgrade request-target starting with // replaces the host in c.req.url, bypassing Origin checks

Affects: upgradeWebSocket. The URL of an upgrade request was built by resolving the request-target against the Host header, so a request-target such as //attacker.example/ws set the host of c.req.url to a client-chosen value while routing still saw /ws. An application that compared Origin with the origin of c.req.url could be bypassed by a page on another site. GHSA-7v5p-43qr-wch5

The host of upgrade requests now comes from the Host header, as for ordinary requests.

Unhandled ECONNRESET on the socket during an asynchronous WebSocket upgrade crashes the process

Affects: upgradeWebSocket. While the application handled an upgrade request, the socket had no error listener. A client that reset the connection during asynchronous middleware caused an unhandled 'error' event and terminated the process. GHSA-qv5m-9pm6-hqp3

Error and close events on the socket are now handled while the application runs, and a pending upgrade is released when the socket closes.

Updates hono from 4.13.13 to 4.13.18

Release notes

Sourced from hono's releases.

v4.13.18

Security fixes

This release includes fixes for the following security issues:

validator() skips validation for requests whose Content-Type parameters are formatted differently

Affects: validator('json') and validator('form') in hono/validator. A Content-Type with whitespace before ;, a trailing ;, or an unusual parameter name was not recognized, so the validator saw an empty object while the handler could read all fields. This completes the fix for GHSA-4h7h-rv7c-7m2v. The validator now decides by the media type alone, as c.req.parseBody() does. GHSA-92p4-j3wq-jmqx

bodyLimit() keeps every transfer chunk of a request body in memory

Affects: bodyLimit() in hono/body-limit. A body sent in very small transfer chunks was retained as one object per chunk, so a request within the configured limit could exhaust memory. The body is now buffered in one array bounded by maxSize. GHSA-39q9-qp46-w8xg

mount() and app.mount() forward a wrong path when a custom getPath adds a prefix

Affects: mount() in hono/mount and app.mount() on 4.13.16 and 4.13.17. With a getPath that prepends a prefix such as the host name, one segment too many was removed from the forwarded path, so middleware scoped inside the mount prefix could be skipped. The prefix is removed from the routed path again. Paths that would change meaning when forwarded now get 400, and an optional regular expression parameter in a mount path throws. GHSA-h25j-2p75-qj33

serveStatic() serves a path that was decoded twice when allowPercentInPath is enabled

Affects: serveStatic() in hono/serve-static and the runtime adapters, only with allowPercentInPath: true. A malformed percent escape in the request path was decoded a second time, so a path that middleware registered on the encoded form did not see could still reach a static file. The file path must now be the same as the routed path, and otherwise the response is 404. GHSA-74fm-fwc7-3fwp

---

Users who rely on validator(), bodyLimit(), mount() with a custom getPath, or serveStatic() with allowPercentInPath are strongly encouraged to upgrade to this version.

Updates undici from 6.29.0 to 6.29.1

Release notes

Sourced from undici's releases.

v6.29.1

Security fixes

High severity

Denial of service via TLS 1.2 certificate-changing renegotiation

CVE-2026-87018 · GHSA-qrxm-fqhp-jwvm

A malicious or compromised HTTPS server could crash the Node.js process by initiating TLS 1.2 renegotiation and presenting a different, CA-trusted certificate whose hostname did not match the requested host. The resulting socket error reached an assertion in undici's HTTP/1.1 and HTTP/2 connection handling. This release handles post-connect certificate errors without terminating the process.

TLS certificate validation bypass through dropped Agent options

CVE-2026-109383 · GHSA-2m5v-pch6-74hx

Agent used a JSON-based clone for constructor options, which silently removed function-valued TLS options such as checkServerIdentity. Applications relying on custom certificate or public-key verification could therefore accept a certificate that the callback was intended to reject. This release preserves TLS options when creating per-origin dispatchers.

Denial of service through excessive Content-Encoding values

CVE-2026-109869 · GHSA-xjj6-f33q-929c

A malicious HTTP server could crash the Node.js process by returning more than five content codings and closing the connection before sending the body. Although fetch() rejected the response, an error from an orphaned internal stream could remain unhandled. This release validates the content-encoding chain before creating the body stream and aborts oversized chains safely.

Medium severity

Denial of service through unbounded EventSource parser state

CVE-2026-109924 · GHSA-4qv8-2p9j-2685

A malicious Server-Sent Events endpoint could exhaust process memory by sending many tiny data: fields without completing an event, or by splitting an unfinished line across many chunks. This release bounds retained EventSource parser state, including field counts, buffered chunks, unfinished-line length, and retained field data.

Denial of service through unbounded automatic WebSocket PONG buffering

CVE-2026-109932 · GHSA-9fm3-97px-rjf6

A malicious WebSocket server could exhaust process memory by flooding the client with PING frames while not reading the automatic PONG responses. undici previously ignored socket backpressure and allowed the outbound queue to grow without bound. This release pauses frame parsing when PONG writes encounter backpressure and resumes after the socket drains.
