CVE-2026-90711 proxy-addr vulnerable to IP spoofing via IPv4-mapped IPv6 trust subnet

proxy-addr is a Node.js module that determines a request's client address behind trusted reverse proxies, and it backs Express req.ip and req.ips. In versions 1.1.0 through 2.0.7, a trust subnet written in IPv4-mapped IPv6 notation with an IPv4-sized prefix, such as ::ffff:10.0.0.0/8 instead of t...

CVE-2026-90711

proxy-addr is a Node.js module that backs Express req.ip and req.ips. In versions 1.1.0 through 2.0.7 , a trust subnet written in IPv4-mapped IPv6 notation with an IPv4-sized prefix (e.g., ::ffff:10.0.0.0/8 instead of /104) is silently accepted, causing every IPv4 address to be treated as trusted...
