Description

Vapor is an HTTP web framework for Swift and middleware is a logic chain between the client and a Vapor route handler. FileMiddleware enables the serving of assets from the Public folder of a project to the client.

Vapor before 4.60.3 is vulnerable to denial of service due to an integer overflow when given invalid range headers while using FileMiddleware. This is patched in 4.60.3.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/vapor/vapor, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update github.com/vapor/vapor to 4.60.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-31005 is resolved across your whole dependency graph.

  3. Workarounds

    Constrain what reaches the vulnerable code: limit the size and shape of untrusted input, isolate the affected component in a sandboxed or least-privileged process, and enable the platform's memory-safety mitigations (ASLR, stack protector, hardened allocator) so an out-of-bounds access is more likely to fail closed than to be exploitable.

Frequently Asked Questions

Vapor is an HTTP web framework for Swift and [middleware](https://docs.vapor.codes/advanced/middleware/) is a logic chain between the client and a Vapor route handler. [FileMiddleware](https://docs.vapor.codes/advanced/middleware/#file-middleware) enables the serving of assets from the Public folder of a project to the client. Vapor before 4.60.3 is vulnerable to denial of service due to an integer overflow when given invalid range headers while using FileMiddleware. This is patched in 4.60.3.
