The Node.js module proxy-addr versions 1.1.0 through 2.0.7 improperly handle IPv4-mapped IPv6 trust subnets with an IPv4-sized prefix, causing them to trust all IPv4 addresses instead of the intended subnet. This allows unauthenticated clients to spoof the X-Forwarded-For header and control the client IP address seen by the application, undermining IP-based access controls, rate limiting, geolocation, and audit logging. The issue was introduced in version 1.1.0 and fixed in version 2.0.8. Users should upgrade to 2.0.8 or later or apply a workaround by correctly specifying the prefix length or using plain IPv4 notation for trust subnets.
