Puma PROXY Protocol v1 Parser Allows Remote Memory Exhaustion
Impact PROXY protocol support for Puma was added in version 5.5.0. When PROXY protocol v1 support is enabled, Puma reads incoming bytes into an internal buffer. It waits for "\r\n" to determine whether a PROXY v1 line is present. If an attacker opens a TCP connection and continuously sends bytes...
Puma PROXY Protocol v1 Accepts Repeated Protocol Headers on Persistent Connections
Impact Puma is vulnerable to source IP spoofing when setremoteaddress proxyprotocol: :v1 is enabled and persistent connections are used. PROXY protocol v1 is a connection-level protocol. Support was added to Puma in v5.5.0. A proxy sends one PROXY header at the beginning of a TCP connection, befo...

curl: CRLF Injection in HAProxy PROXY Protocol via CURLOPT_HAPROXY_CLIENT_IP allows IP spoofing and protocol injection
Summary: CURLOPTHAPROXYCLIENTIP introduced in curl 8.2.0 accepts arbitrary strings without any validation or sanitization before injecting them into the HAProxy PROXY protocol v1 header. An attacker who can influence the value passed to this option e.g., through a web application that proxies...
