CVE-2026-47736 Puma PROXY Protocol v1 Parser Allows Remote Memory Exhaustion

Puma is a Ruby/Rack web server built for parallelism. From 5.5.0 until 7.2.1 and 8.0.2, when PROXY protocol v1 support is enabled, Puma reads incoming bytes into an internal buffer while waiting for CRLF to determine whether a PROXY v1 line is present, allowing an attacker that continuously sends...

TsDProxy: X-Forwarded-For header injection allows IP spoofing in proxied requests to backend services

Description The HTTP reverse proxy handler in tsdproxy does not strip the X-Forwarded-For or X-Real-IP header from incoming requests before calling r.SetXForwarded. This allows an authenticated Tailscale user to inject arbitrary X-Forwarded-For values that are forwarded verbatim to backend...
