* fix(lib): ensure issued challenges don't get double-spent Closes #1002 TL;DR: challenge IDs were not validated at time of token issuance. A dedicated attacker could solve a challenge once and reuse it across multiple sessons in order to mint additional tokens. With the advent of store based challenge issuance in #749, this means that these challenge IDs are only good for 30 minutes. Websites using the most recent version of Anubis have limited exposure to this problem. Websites using older versions of Anubis have a much more increased exposure to this problem and are encouraged to keep this software updated as often and as frequently as possible. * docs: update CHANGELOG Signed-off-by: Xe Iaso <me@xeiaso.net> --------- Signed-off-by: Xe Iaso <me@xeiaso.net>

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, connect to anubis.techaro.lol.
