CVE-2026-5119 (GCVE-0-2026-5119)

Vulnerability from cvelistv5 – Published: 2026-03-30 05:35 – Updated: 2026-05-06 14:52

Title

Libsoup: libsoup: information disclosure via cleartext transmission of cookies during https tunnel establishment

Summary

A flaw was found in libsoup. When establishing HTTPS tunnels through a configured HTTP proxy, sensitive session cookies are transmitted in cleartext within the initial HTTP CONNECT request. A network-positioned attacker or a malicious HTTP proxy can intercept these cookies, leading to potential session hijacking or user impersonation.

Severity ?

5.9 (Medium)
