CVE-2026-121554

cordova-plugin-advanced-http 1.5.0 through 3.3.1 contains an information disclosure vulnerability that leaks cookies to third-party hosts because the JavaScript layer passes jar-built Cookie headers as ordinary request headers. When a request is redirected to another host via an open or attacker-influenced redirect, native iOS and Android stacks forward the Cookie header, letting attackers hijack user sessions.
