"According to the versions of the libsoup packages installed, the EulerOS installation on the remote host is affected by
the following vulnerabilities :

    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.(CVE-2026-5119)

Tenable has extracted the preceding description block directly from the EulerOS libsoup security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
