Xe Iaso 0491f1fac2 fix: patch GHSA-6wcg-mqvh-fcvg (#1616)
* fix: patch GHSA-6wcg-mqvh-fcvg

PR https://github.com/TecharoHQ/anubis/pull/1015 added the ability for
reverse proxies using Anubis in subrequest auth mode to look at the path
of a request as there are many rules in the wild that rely on checking
the path. This is how access to things like robots.txt or anything in the
.well-known directory is unaffected by Anubis.

However this logic was also enabled for non-subrequest deployments of Anubis,
meaning that a specially crafted request could include a /.well-known/
path in it and then get around Anubis with little effort.

This fix gates the logic behind a new plumbed variable named subrequestMode
that only fires when Anubis is running in subrequest auth mode. This
properly contains that workaround so that the logic does not fire in
most deployments.

Overview

Anubis is a Web AI Firewall Utility that weighs the soul of your connection using one or more challenges in order to protect upstream resources from scraper bots.

This program is designed to help protect the small internet from the endless storm of requests that flood in from AI companies. Anubis is as lightweight as possible to ensure that everyone can afford to protect the communities closest to them.

Anubis is a bit of a nuclear response. This will result in your website being blocked from smaller scrapers and may inhibit "good bots" like the Internet Archive. You can configure bot policy definitions to explicitly allowlist them and we are working on a curated set of "known good" bots to allow for a compromise between discoverability and uptime.

In most cases, you should not need this and can probably get by using Cloudflare to protect a given origin. However, for circumstances where you can't or won't use Cloudflare, Anubis is there for you.

If you want to try this out, visit the Anubis documentation site at anubis.techaro.lol.
