CVE-2026-6410

### 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.
