Summary Vulnerability in prox-addr Node.js module Vulnerability Details CVEID:CVE-2026-90711 DESCRIPTION: 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...

CVE-2026-115729 @pdfme/common 5.5.10 before 6.2.6 SSRF via isUrlSafeToFetch Bypass

@pdfme/common from 5.5.10 before 6.2.6 contains a server-side request forgery vulnerability that allows attackers to bypass the isUrlSafeToFetch denylist in getB64BasePdf. Attackers can supply basePdf URLs using IPv4-mapped IPv6, ::, NAT64 or localhost alias hostnames to read loopback, internal o...

proxy-addr: proxy-addr vulnerable to IP spoofing via IPv4-mapped IPv6 trust subnet

A flaw was found in proxy-addr. When an application defines trusted proxy subnets using IPv4-mapped IPv6 addresses with an improper prefix length, the subnet parser fails open and erroneously treats all incoming network addresses as trusted. A remote, unauthenticated attacker can exploit this...
