From ce8929cabe27c7cf0bfb21b47786c7442ffb3712 Mon Sep 17 00:00:00 2001 From: Ivan Gabaldon Date: Sat, 9 Aug 2025 23:03:30 +0200 Subject: [mod] limiter: trusted proxies (#4911) Replaces `x_for` functionality with `trusted_proxies`. This allows defining which IP / ranges to trust extracting the client IP address from X-Forwarded-For and X-Real-IP headers. We don't know if the proxy chain will give us the proper client address (REMOTE_ADDR in the WSGI environment), so we rely on reading the headers of the proxy before SearXNG (if there is one, in that case it must be added to trusted_proxies) hoping it has done the proper checks. In case a proxy in the chain does not check the client address correctly, integrity is compromised and this should be fixed by whoever manages the proxy, not us.
