CVE-2026-27959

A flaw was found in Koa’s ctx.hostname API used in Node.js applications. The function incorrectly parses specially crafted HTTP Host headers containing an @ character, which can cause the extracted hostname value to differ from the intended origin. An attacker can exploit this behavior by sending...

CVE-2026-27959

Koa (Node.js) prior to versions 3.1.2 and 2.16.4 exposes a vulnerability in ctx.hostname: it naively parses the Host header and returns an attacker-controlled value when the header contains an invalid RFC 3986 hostname (e.g., with a @). This can affect URL generation, password reset links, email ...
