@​fastify/static vulnerable to route guard bypass via encoded path separators

CVE-2026-6414 / GHSA-x428-ghpx-8j92

More information

Details

Impact

@fastify/static v9.1.0 and earlier decodes percent-encoded path separators (%2F) before filesystem resolution, but Fastify's router treats them as literal characters. This creates a routing mismatch: route guards on /admin/* do not match /admin%2Fsecret.html, but @​fastify/static decodes it to /admin/secret.html and serves the file.

Applications that rely on route-based middleware or guards to protect files served by @​fastify/static can be bypassed with encoded path separators.

Patches

Upgrade to @fastify/static >= 9.1.1.

Workarounds

None. Upgrade to the patched version.

Severity

  • CVSS Score: 5.9 / 10 (Medium)
  • Vector String: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N

@​fastify/static vulnerable to path traversal in directory listing

CVE-2026-6410 / GHSA-pr96-94w5-mx2h

More information

Details

Impact

@fastify/static v9.1.0 and earlier serves directory listings outside the configured static root when the list option is enabled. A request such as /public/../outside/ causes dirList.path() to resolve a directory outside the root via path.join() without a containment check.

A remote unauthenticated attacker can obtain directory listings for arbitrary directories accessible to the Node.js process, disclosing directory names and filenames that should not be exposed. File contents are not disclosed.

Patches

Upgrade to @fastify/static >= 9.1.1.

Workarounds

Disable directory listing by removing the list option from the plugin configuration.

Severity

  • CVSS Score: 5.3 / 10 (Medium)
  • Vector String: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N
