A new reported NGINX 0 day vulnerability dubbed nginx-poolslip (by NebSec) is worth keeping an eye on if your homelab uses NGINX, NGINX Proxy Manager, Docker reverse proxies, or a public-facing gateway.

The report says the issue affects NGINX 1.31.0 and involves request memory pool handling, especially around dynamic variable parsing and rewrite-style configuration logic. For homelab setups, the most relevant areas to check are custom reverse proxy rules, old rewrite blocks, map directives, proxy variables, and regex captures like $1 and $2.
