[Kubernetes] Ingress nginx annotation injection causes arbitrary command execution

This vulnerability impacts kubernetes setups using NGINX as the ingress controller via [ingress-nginx](https://github.com/kubernetes/ingress-nginx). At first I wanted to blame this one on block-listing when they should have used an allow-list, but its not quite that, but it is basically just a missed edge-case that allows for code execution.
 

Usurping Mastodon instances - mastodon.so/cial [CVE-2023-42451]

Normalization gone wrong, Mastodon, when attempting to normalize a domain would intend to remove any trailing `/`from it, however they did this using `.delete("/")` which removes all `/` characters from the string instead of just a trailing `/`. This meant that someone could use an account like `someone@mastodon.so/cial` to spoof the account `someone@mastodon.social`.
