CVE-2026-5119

MEDIUM 5.9 ALL-YEARS

Published 2026-03-30 · Last modified 2026-06-09 · redhat · NVD: Modified

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.

    • vendor fix: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Vendor guidance
    • workaround: To mitigate this issue, ensure that all HTTP proxies used for HTTPS tunnels are trusted and operate within a secure network. Avoid configuring applications to use untrusted HTTP proxies. If feasible, configure applications to bypass proxies for sensitive connections or utilize a secure proxy solution that encrypts the entire communication channel. A service restart or application reload may be required for changes to take effect.
